------------------------------------
Summary: [New Feature] Add data connector support for remote
datasources
Key: HIVE-24396
URL: https://issues.apache.org/jira/browse/HIVE-24396
Project: Hive
Issue Type: Improvement
Components: Hive
Reporter: Naveen Gangam
Assignee: Naveen Gangam
This feature work is to be able to support in Hive Metastore to be able to
configure data connectors for remote datasources and map databases. We
currently have support for remote tables via StorageHandlers like
JDBCStorageHandler and HBaseStorageHandler.
Data connectors are a natural extension to this where we can map an entire
database or catalogs instead of individual tables. The tables within are
automagically mapped at runtime. The metadata for these tables are not
persisted in Hive. They are always mapped and built at runtime.
With this feature, we introduce a concept of type for Databases in Hive. NATIVE
vs REMOTE. All current databases are NATIVE. To create a REMOTE database, the
following syntax is to be used
CREATE REMOTE DATABASE remote_db USING <dataconnector> WITH DCPROPERTIES (....);
Will attach a design doc to this jira.
