This document describes how to setup the HBase Connector to run SQL queries against HBase. + +The connector can operate in upsert mode for exchange changelog messages with the external system using a primary key defined on the DDL. But the primary key can only be defined on the HBase rowkey field. If the PRIMARY KEY clause is not declared, the HBase connector will take rowkey as the primary key by default. + Review comment: I think `upsert mode` is not an API, but a general terminology which indicates it is updating by key. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
