Ruby 3 : New features

Hi, This is Shubham Mishra from India,  this is the part of Ruby on Rails exploration journey.  In this post we will discuss about the ruby's some special concepts and I am sure you will get excited to make your hands dirty with those code, so why to wait let's get started...

The most recent significant version of the Ruby programming language is Ruby 3. It has a number of interesting new features and advancements and was published on December 25, 2020. We will examine some of Ruby 3's updated features in this blog.

-> Ractors Ruby 3 introduces Ractors, also referred to as Ruby Actors. They enable us to execute several threads of code concurrently without having to share memory or state. As a result, concurrent and parallel programming is made simpler, which can enhance performance and scalability. Ractors are simple to use and integrate with existing code because they are designed on top of the Thread API that already exists.

-> Type Profiling Type profiling, which is a means to examine how programmes behave at runtime and determine the kinds of objects at runtime, is introduced in Ruby 3. By helping the Ruby interpreter to produce more effective code, this can help performance. Type profiling is an optional feature that can be turned on or off at runtime.

-> Enhancing Performance A new virtual machine (MJIT) that can convert Ruby code into machine code in real time as well as performance-enhancing changes to the garbage collector are among the performance enhancements in Ruby 3. These enhancements can speed up and improve the effectiveness of Ruby programmes.

-> Pattern Matching With the help of the new pattern matching functionality in Ruby 3, we can quickly compare data structures and retrieve values. It can increase readability and maintainability of code and make it simpler to design code that interacts with complex data structures.

-> Endless Method Definition Using Ruby 3's new endless method declaration syntax, we can define methods without mentioning an end keyword. This can simplify the syntax for defining methods and increase the readability of the code.

-> Immutable Strings In Ruby 3, strings are immutable by default. This means that once a string is created, its value cannot be changed. Immutable strings can improve performance and prevent unexpected changes to data.

In conclusion, Ruby 3 is a noteworthy update that adds a number of fresh features and performance enhancements. A few of the new features that make Ruby 3 a potent and contemporary programming language include Ractors, type profiling, increased efficiency, pattern matching, unlimited method definition, and immutable strings. Regardless of your level of experience as a developer, Ruby 3 is undoubtedly worth investigating.

Rails Postgresql Query timeout set and skip during migration

Hi, I am  Shubham Mishra  from India,  this is the part of  Ruby on Rails  exploration journey.  In this post we will discuss about the rails DB (Postgresql) query time out setting and how can we avoid this timeout setting during migration and I am sure you will get excited to make your hands dirty with those code, so why to wait let's get started... Question: Rails and postgresql I want to set query timeout to 10 sec but skip to check this timeout setting during rails migration how can i achieve? Answer: To set a query timeout of 10 seconds for PostgreSQL in a Rails application, you can use the statement_timeout configuration option in your database.yml file. Here is an example configuration that sets the query timeout to 10 seconds: This will set the query timeout to 10 seconds for all queries executed by the PostgreSQL adapter in the production environment. To skip checking the query timeout setting during Rails migrations, you can use a custom connection adapter tha

Rails Sync Postgresql and Elasticsearch Database of a Model

Hi, This is  Shubham Mishra  from India,  this is the part of  Ruby on Rails  exploration journey.  In this post we will discuss about how can we keep Postgresql (a SQLDB) and Elasticsearch (a nonSQL DB) with the help of a background job processor and I am sure you will get excited to make your hands dirty with those code, so why to wait let's get started... Most of the time due to increase in DB record size we try to split our DB into two DB based on the requirement like one is Transaction oriented (SQL DB) and another Search oriented (Non SQL DB) with limited data. In my case we have Postgresql for storing all the records and used for entire business operation and for Search support we have elasticsearch with minimum indexes (tables) and their entire documents. For better understanding lets consider in PG DB we have Employee table with id, name, dob, address etc and some more other tables, whereas in Elasticsearch we have only Employee index (table) with all its documents dupli

Ruby on Rails configure CORS setting with rack cors gem

Hi, This is  Shubham Mishra  from India,  this is the part of  Ruby on Rails  exploration journey.  In this post we will discuss about the CORS concepts and I am sure you will get excited to make your hands dirty with those code, so why to wait let's get started... What is CORS? Cross-Origin Resource Sharing, sometimes known as CORS, is a security feature built into web browsers that enables web servers to manage which domains can access their resources. It is used to stop rogue websites or programmes from gaining unauthorised access to a web server's resources. In plainer terms, a web browser will submit a CORS request to the server whenever a web application makes a request to a domain other than the one it is currently executing on in order to determine whether it is authorised to access the resources of that domain. The browser can retrieve the resources and show them to the user if the server agrees to the request. Why CORS is important? If CORS is not used, malici
