The Couchbase SQL Importer is a Java-based command line tool designed to facilitate the transfer of data from relational databases (RDBMS) to Couchbase by converting SQL table rows into JSON documents and importing them into Couchbase. Each table row is transformed into a JSON document where table columns become JSON attributes, and documents are assigned keys based on the table name and a counter. The tool creates views to enable queries for imported documents by type or primary key, allowing users to efficiently navigate and manage data within Couchbase. To utilize the tool, users must download the necessary jar files, configure a properties file for database connections and import options, and execute the tool through a specified Java command. The tool serves as a foundational step for experimenting with data in Couchbase, with the possibility of further customization or enhancement to suit specific application needs.
