Redis Connection: SELECT index

Redis SELECT Command

Redis SELECT command is used to select the DB with having the specified zero-based numeric index. New connections always use DB 0.

Here are some common uses and scenarios for the "SELECT index" command:

• Database Selection: Switches the client connection to a specific logical database identified by the given index, allowing for organized data management.
• Data Isolation: Provides isolation between different datasets by enabling operations on separate databases within the same Redis instance.
• Multi-Database Management: Facilitates the management of multiple databases, allowing applications to segment and categorize data effectively.
• Environment Separation: Useful for separating environments, such as development, testing, and production, by using different databases within the same server.
