Description

Based on analysis of market popularity, the following 9 database/storage connectors are suggested to be supported in SeaTunnel.

Database/Storage Connectors Tracking

Type Connector Contributer Status PR
Source/Sink Azure Cosmos DB @SalvadorN323 (Sink) Partial
Source/Sink CockroachDB @sug-ghosh Claimed
Source/Sink Amazon DocumentDB Todo
Source/Sink Firebase (Realtime Database) Todo
Source/Sink Couchbase Todo
Source/Sink Sybase Todo
Source/Sink Ingres Todo
Source/Sink SingleStore (MemSQL) @852511489 Doing #10521
Source/Sink Airtable @kuleat Done #10469

Context & Details

  1. Azure Cosmos DB: Highly popular cloud-native database on Azure (NoSQL / Multi-model).
  2. CockroachDB: Distributed SQL. Compatible with PostgreSQL wire protocol but dedicated connector allows optimized features.
  3. Amazon DocumentDB: AWS managed document database (MongoDB-compatible).
  4. Firebase (Realtime Database): distinct from the existing google-firestore connector.
  5. Couchbase: Enterprise-grade NoSQL document store.
  6. Sybase: Legacy RDBMS widely used in financial sectors.
  7. Ingres: Heritage relational database system.
  8. SingleStore (formerly MemSQL): High-performance real-time analytics database (HTAP).
  9. Airtable: Low-code Database / Spreadsheet, popular as a data source.

Research direction
This is a meta issue tracking multiple connector additions. For first time contributors, it is advisable to focus on one specific connector from the Todo list (e.g., Amazon DocumentDB, Couchbase, Sybase, Ingres, Firebase). Examine existing connector implementations such as the Airtable connector (PR #10469) and the SingleStore connector (PR #10521) located in the seatunnel connectors/ directory. Read the contribution guide and understand the connector interface. Before starting, check the issue comments to verify the connector is not already claimed. The project uses Java and the SeaTunnel connector API. Start by setting up the development environment and implementing a basic source and sink for the chosen database.
