Apache Solr vs Elasticsearch: How Are They Different? How Do You Decide? Part 2

Apache Solr vs Elasticsearch: How Are They Different? How Do You Decide? Part 2

by RADU SIMILEANU on Mar 16 2018

And I'm back, as promised, with 5 more key differences meant to help you solve your Apache Solr vs Elasticsearch dilemma.

To help you properly evaluate the 2 open source search engines and, therefore, to identify the perfect fit for your own use case and your project's particular needs.

 

6. Node Discovery

Another aspect that clearly differentiates the 2 search engines is the way(s) they handle node discovery.That is, whenever a new node joins the cluster or when there's something wrong with one of them, immediate measures, following certain criteria, need to be taken.

The 2 technologies handle this node-discovery challenge differently:

 

  1. Apache Solr uses Apache Zookeeper — already a “veteran”, with plenty of projects in its “portfolio” —  requiring external Zookeper instances (minimum 3 for a fault-tolerant SolrCloud cluster).
  2. Elasticsearch relies on Zen for this, requiring 3 dedicated master nodes to properly carry out its discovery “mission”

 

7. Apache Solr vs Elasticsearch: Machine Learning

Machine learning has a way too powerful influence on the technological landscape these days not to take it into consideration in our Apache Solr vs Elasticsearch comparison here.

So, how do these 2 open source search engines support and leverage machine learning algorithms?

 

  1. Apache Solr, for instance, comes with a built-in dedicated contrib module, on top of streaming aggregations framework; this makes it easy for you to use machine-learning ranking models right on top of Solr
  2. Elasticsearch comes with its own X-Pack commercial plugin, along with the plugin for Kibana (supporting machine learning algorithms) geared at detecting anomalies and outlines in the time series data 

     

8. Full-Text Search Features 

In any Apache Solr vs Elasticsearch comparison, the first one's richness in full-text search related features is just... striking!

Its codebase's simply “overcrowded” with text-focused features, such as:

 

  • the functionality to correct user spelling mistakes
  • a heavy load of request parsers
  • configurable, extensive highlight support
  • a rich collection of request parsers

     

Even so, Elasticsearch “strikes back” with its own dedicated suggesters API. And what this feature does precisely is hiding implementation details from user sight, so that we can add our suggestions far more easily.

And, we can't leave out its highlighting functionality (both search engines rely on Lucene for this), which is less configurable than in Apache Solr.

 

9. Indexing & Searching: Text Searching vs Filtering & Grouping

As already mentioned in this post, any Apache Solr vs Elasticsearch debate is a:

Text-search oriented approach vs Filtering and grouping analytical queries type of contrast.

Therefore, the 2 technologies are built, from the ground up, so that they approach different, specific use cases:

 

  1. Solr is geared at text search
  2. Elasticsearch is always a far better fit for those apps where analytical type of queries, complex search-time aggregations need to be handled

     

Moreover, each one comes with its own “toolbox” of tokenizers and analyzers for tackling text, for breaking it down into several terms/tokens to be indexed.

Speaking of which (indexing), I should also point out that the two search engine “giants” handle it differently:

 

  1. Apache Solr has the single-shard join index “rule”; one that gets replicated across all nodes (to search inter-document relationships)
  2. Elasticsearch seems to be playing its “efficiency card” better, since it enables you to retrieve such documents using top_children and has_children queries

     

10. Shard Placement: Static by Nature vs Dynamic By Definition

Shard replacement: the last test that our two contestants here need to pass, so you can have your final answer to your “Apache Solr vs Elasticsearch” dilemma.

In this respect, Apache Solr is static, at least far more static than Elasticsearch. It calls for manual work for migrating shards whenever a Solr node joins or leaves the cluster. 

Nothing impossible, simply less convenient and slightly more cumbersome for you:

 

  • you'll need to create a replica 
  • wait till it synchronizes the data
  • remove the “outdated” node

     

Luckily for you, Elasticsearch is not just “more”, but “highly” dynamic and, therefore, far more independent.

It's capable to move around shards and indices, while you're being granted total control over shard placement:

  • by using awareness tags, you get to control where those shards should/shouldn't be placed
  • by using an API call you can guide Elasticsearch into moving shards around on demand

The END! Now if you come to think about it, my 10-point comparative overview here could be summed up to 2 key ideas worth remembering:

 

  1. go for ApacheSolr if it's a standard text-search focused app that you're planning to build; if you already have hands-on experience working with it and you're particularly drawn to the open-source philosophy
  2. go for Elasticsearch if it's a modern, real-time search application that you have in mind; one perfectly “equipped” to handle analytical queries. If your scenario calls for a distributed/cloud environment (since Elastic is built with out-of-the-ordinary scalability in mind)

10 Best Headless CMS in 2020, That Cover Most of Your Requirements (Part 1)
Overwhelmed with options? Are you building your first (e-commerce) headless CMS and you don't know what headless CMS platform to choose?  What are the best headless CMS in 2020, so you can at least narrow down your choices and start... somewhere? Which system matches most of your feature requirements? Here's a top 10: 1. But First: What Is a Headless CMS, More Precisely? Relax, I won't bore you with too many details — we already have an in-depth post on the differences between headless and traditional CMS. So, if we were to sum up the concept in just a few words, we could say that: A headless content management system is an architecture where content is separated from the presentation layer (the client-side front-end). Meaning that you get to create, store, and edit "raw" content (with no design or layout) in the backend and deliver it wherever needed —wearable, mobile app, website — via API. In short, what you get in a headless architecture is: a database to store your content in a dashboard for editing your content Source: Zesty.io As for the "head" that serves your content to the end-user : you're free to build your own front-end, from the ground up … and even multiple front-ends, if needed, that will all use calls from the API to retrieve and display content 2. … Then What's a Decoupled CMS? Headless CMS vs decoupled CMS: what's the difference? And why headless over decoupled? The role that the API plays… That's what makes the difference (and why you'd want to go for a headless approach): If, in a decoupled architecture, the API plays the role of an intermediary between back-end and front end, in a headless architecture the API can be used by any of the front-end portions for pulling data. In other words, a decoupled CMS does come with a built-in front-end delivery layer, that you can rely on, but a headless approach is an API-driven content repository. Which gives you more flexibility for delivering content to any type of display layer. … to multiple "heads". You're free to distribute it wherever it needs to get displayed. 3. Why Choose a Headless CMS? Top 9 Benefits Before I "divulge" the best headless CMS in 2020 to you, here's a shortlist of the key advantages of using a headless CMS software: you get to engage your customers with personalized content across an entire network of digital channels, at different stages in their journey you can deliver richer digital experience, tailored to each channel you gain platform independence you're free to choose your technology of choice you benefit from cross-platform support you get to manage your content from a central location and distribute it to multiple platforms/IoT-connected devices, in a universal format you're free to manage all your platforms from one interface your development team gets to choose the development framework of their choice, integrate new technologies and, overall… innovate you're free to redesign as often as you need to, without the dread of re-implementing your entire CMS from the ground up     4. … And When Should You Use It? 5 Best Use Cases  How do you know for sure that you need to adopt this approach? You know it because your scenario describes one of the following use cases for headless CMS: you're building a site using a technology you're familiar with you're building a website with a static site generator you're building a JS-based website or web app you're building a native mobile app you're building an e-commerce site and you know that the commerce platform you're using won't… cut the mustard as a CMS; or you need to enrich product info in your online store 5. What Are the Best Headless CMS in 2020? Top 10 "Which CMS should I use?" you wonder. "The one that meets most of your requirements…" So, you should start by pinning them down. What features are you looking for in a CMS? Maybe you need a system that should: be straightforward and easy to use for the marketers/non-technical people in your team be built on… Node be highly customizable and editable for your content team to be able to change overlay text, logo, background video/image be simple to set up integrate easily with Gatsby support multi-site setups not be tied up to (just) one specific database provide ease of content entry and rich-text support provide a granular permission system provide native support for content types What are the features that your project couldn't live without? Now, with that list of "mandatory" features at hand, just drill down through your top headless CMS options in 2020. Here they are: 5.1. Storyblok A purely headless CMS that ships with a visual editor, as well. Why would you go for Storyblok? What makes it one of the best headless CMS in 2020? it provides the experience of a page builder for all those non-technical users in your team: editors get to manage content via a more user-friendly interface it grants your developers easy access to the APIs they need 5.2. Prismic Its major selling point? It allows you to choose your own language, framework, technology… And these are the 3 good reasons to go with Prismic as your headless CMS: it allows you to model your content schema and to add your content you're free to choose whatever framework that meets your feature needs: React, Vue, Next, Nuxt, Node, Gatsby… you're free to choose either GraphQL or RESTful API to query content 5.3. Drupal 8 Headless CMS   Another great option is to exploit Drupal's headless capabilities and pair them with the JavaScript framework of your choice. Here are some of the best reasons why you'd use a Drupal 8 API-first architecture: Drupal's a mature and enterprise-level headless solution backed by a wide community, used by more than 1 million sites globally; you get to tap into its massive module collection and even create new custom ones to extend your website's functionality its JSON:API follows the JSON:API specification; developers in your team can start using the API even if they're not experts in working with Drupal you get to load your GraphQl schemas straight from your Drupal content repository; there's a specialized module for this: the GraphQL module you get to use all of  Drupal's famed features (granular access to content, processes, workflows, modules, etc.) right away; you get them out-of-the-box since the REST API is… rooted deep into Drupal 5.4. Strapi, One of the Best headless CMS for Gatsby. It's an open-source Node.js headless CMS, a "host it yourself" one, that allows you to build Node.js apps in… minutes. Why would you use it? because it generates available RESTful API or uses GraphQL shortly after installation, making data available via customizable API because it allows your developers to invest all their resources in writing reusable app logic (instead of having to use some of that time to build an infrastructure) because it's fully JavaScript because it supports plugins that extend the platform's functionality because it's open-source: you'll find the entire codebase on GitHub  5.5. Contentful  Looking for a platform-agnostic solution? A… content delivery network that would enable your development team to manage and distribute (and reuse) content to multiple channels? Then this is the API-driven headless CMS you're looking for. Here are 6 other reasons why you'd want to put Contentful on your shortlist: consistent APIs easy to set up you're free to create your own models easy to use: ships with a robust, non-technical, user-friendly UI you get to add custom plugins quick and easy you get to set your own schemas to get displayed the way you want them to, across different apps Good to know! There's even a Shopify extension available. What it does is connect your online store to your content, stored in Contentful. And if you'll need help with building, fine-tuning, and integrating your content hub, we're ready to tweak Contentful to your needs.  END of Part 1!

Magento vs Shopify 2020: Which Platform Should You Use for Your eCommerce Store? And Why?
A bit stuck? Are you looking to roll out your online store, but… you’re struggling with a Magento vs Shopify 2020 dilemma? Which solution works best for the size and the type of your eCommerce business? Which one covers most of your feature needs? In today’s post you’ll get your answers to the following questions: How are they different? Why would you choose Shopify over Magento? What are its strongest selling points? What are the cons of Shopify? What are the pros and cons of Magento vs Shopify? Which eCommerce platform works best for your type of business? 1. What Are the Major Differences Between Magento and Shopify? The main reason why you’re torn between Magento and Shopify is that: You don’t have a clear picture of the essential differences between them. So, let me expose them to you: 1.1. Magento is an eCommerce solution for enterprise-level online stores. It’s robust and flexible enough to power fully customized eCommerce websites, built from scratch — that you can further expand to fit your growth plan — by teams of Magento developers. 1.2. Shopify, on the other hand, is self-managed.  You don’t need any specialized skills — or server-side techs — to set up a Shopify store.  A front-end developer and a designer, at most, will do. “How easy is it to use Shopify?” Shopify is best-known for being beginner-friendly.  In short, the “Magento vs Shopify” dilemma comes down to: Flexibility and customization vs Ease of use. Which one's more important to you? 2. Magento vs Shopify 2020: Why Would You Choose Shopify? What makes Shopify a candidate for the title of “the best solution for creating an eCommerce website in 2020"? Here’s why Shopify could be the better choice for your online store: you have no (or limited) coding skills the idea of having a huge app marketplace at your disposal to browse through sounds tempting to you you need to get your e-Store up and running… now: the drag-and-drop website builder allows you to set up a new store in… minutes it’s an end-to-end eCommerce solution that you’re looking for, one that enables you to roll out and manage your online store with no technical experience it’s easier to use: its interface is famous for being particularly user-friendly you run a small or medium-sized eCommerce business page loading time is critical for you: Shopify’s just… fast Overall, it’s much less of a headache than Magento and usually the go-to option for small eCommerce business owners, with no web development experience, who need to get their websites rolled out fast. 3. What Are the Cons of Shopify? What could make you hesitate to choose Shopify for your eCommerce website? For there are, indeed, some limitations to consider before going for this particular platform:   You’d be trading some of the control over your online store for… ease of use and the convenience of setting up your eStore quick and easy, with no technical expertise   You do get a huge collection of plugins to choose from but… they all come with a price tag on; one that you’ll need to consider when planning out your budget   You won’t be able to customize every single aspect of your website. By comparison, Magento puts no limitation on the configurations that you can make to your site   Shopify provides you with weaker SEO features   It charges a transaction fee per… sale   4. Why Would You Choose Magento over Shopify? When dealing with a Magento vs Shopify 2020 dilemma, what could make you opt for Magento? Lots of reasons... Here are the strongest ones:   It enables you (or your team of Magento developers in Toronto) to customize everything about your eCommerce website, from theme to checkout process, to main menu, to email template, to...   You get to build custom functionality for your website, that’s not available on the market   You have lots of extensions available to choose from — Magento being open-sourced — and to customize your online store   You benefit from its strong SEO capabilities   You get to tap into its multi-store functionality: Magento enables you to manage all your online stores from one central dashboard   “In fact, according to eCommerce Platforms research Magento SEO scores 95 out of 100, and that is great result!” (source: Cart2Cart ) In short, you’d want to go with Magento because it enables you to build pretty much anything that you might need for your eCommerce website. 5. What About the Cons of Using Magento? For you need to be aware of the disadvantages of using this eCommerce solution, as well, before you make any decision. Now, here are the most… discouraging ones:   Building a fully customized website in Magento takes time and requires web development experience and Magento expertise; you can’t get away without a team of back-end Magento developers to handle the whole process and all the customization wok   You do have a large and thriving community to rely on, but no 24/7 dedicated support (like you have with Shopify)   You’ll need to optimize your Magento website on a regular basis to make sure it keeps performing at its best   You’ll need to take into account the cost of all the extensions that you might want to add, of the web hosting service, and the Magento expertise needed   6. Magento 2 vs Shopify vs... Shopify Plus: Which One’s the Best Fit? Considering that, starting June 2020, Magento 1.0 is no longer supported, your Magento vs Shopify 2020 dilemma turns into: “Magento 2 vs Shopify”. What new features does Magento 2 bring to the debate? simplified navigation (even) better customization capabilities better performance a more admin-friendly panel drag-and-drop layout editing improved checkout  “And what about Shopify Plus?” you might then ask yourself. Here are some of the enhancements that Shopify Plus ships with, so you can see for yourself whether it’s the best fit for what you’re looking for:   It gives you greater control over your online store: you gain more customization freedom   It’s robust enough to handle more than 10,000 transactions per minute, which makes it a viable alternative to Magento 2 for enterprise-level eCommerce businesses   You’re free to edit your checkout page (a feature that’s not available in Shopify)   You get your own launch manager: basically, a dedicated Shopify Plus team will handle everything for you, from implementing the custom Shopify theme that you need to code writing   7. Which Commerce Platform Works Better for Your Type of eCommerce Business? Now that you have a clear(er) picture of the pros and cons of Magento vs Shopify, how do you know which one’s the best fit for you? For your business goals and size? It’s simple: just pick the answer(s) that best fits your scenario from the following ones: You’ll want to use Magento if: you have a large product catalog your customization  needs are… above the average (i.e. complex product configurations): you want a fully customized online store built from the ground up you need a commerce platform robust enough to support your entire network of vendor/supplier fulfillment channels you have qualified Magento developers in your team (or the budget to hire some professionals, who know what they’re doing) You’ll want to use Shopify over Magento in 2020 if: it’s a small to medium product catalog that you need to set up being able to integrate/cross-sell on multiple platforms is a crucial feature for you you need to get your storefront online as quickly as possible Does this head-to-head help you with your Magento vs Shopify 2020 dilemma?  No matter which one’s the “winner”, the next question stays the same: “How do I get my Shopify/ Magento website built and suited to my needs?"
