Introduction
In the world of web development, databases play a critical role in storing and managing the data that powers applications. Within a database, tables organize this data into rows and columns, making it easier to retrieve and manipulate.
However, as tables grow larger, finding specific pieces of information can become slow and inefficient. This is where indexes
come into play.
Indexes
Indexes are special database objects that improve the speed of data retrieval operations, much like an index in a book helps you quickly find the page you're looking for.

Connection indexes
Let's use the connection.indexes
method from ActiveRecord
to retrieve the indexes for the desired table.
ActiveRecord::Base.connection.indexes(:your_table)
Connection adapters
This will return an array of ActiveRecord::ConnectionAdapters::IndexDefinition
objects, each representing an index on the your_table table.
Besides, this will print the name, columns, and uniqueness of each index on the users table.
