Consider supporting PostgreSQL/openGauss search path feature #17204

Feature Request

Is your feature request related to a problem?

No.

Describe the feature you would like.

After issue #14004 is completed, ShardingSphere has supported SQL such as CREATE SCHEMA, ALTER SCHEMA and DROP SCHEMA, and allows users to specify schema modifiers when executing SQL, such as:

SELECT * FROM test.t_order;

This SQL will query the data of the t_order table from the test schema.

In order to improve the experience of using PostgreSQL/openGauss schema, we need to support the search_path parameter. Through the SET SEARCH_PATH TO test, public; statement, users can dynamically switch the schema without going through schema.t_order. For more detail about search_path, we can refer this doc——https://www.postgresql.org/docs/14/ddl-schemas.html#DDL-SCHEMAS-PATH.

@strongduanmu Hi,i want to do this. Can you assign me? Thx

strongduanmu commented 2 years ago

@zjcnb Of course. We can consider implementing the global search path first by adding a configuration.

  • [ ] Add search path configuation for server.yaml props
  • [ ] Refactor metadata structure
  • [ ] Check all schemas are consistent
  • [ ] Set search path to jdbc url
  • [ ] Refactor get schema logic
  • [ ] Clear up session search path

Ok,I'd like to try that.
