-------------------------------------
Summary: Add source fields for NOTIFICATION_LOG table
Key: HIVE-28713
URL: https://issues.apache.org/jira/browse/HIVE-28713
Project: Hive
Issue Type: New Feature
Reporter: Quanlong Huang
HMS event consumers like Impala will also generate HMS events in HMS
operations. They would like to skip processing such self-generated events.
However, currently in the NOTIFICATION_LOG table, there are no fields to
identify where the event comes from.
{noformat}
Table "public.NOTIFICATION_LOG"
Column | Type | Collation | Nullable | Default
----------------+------------------------+-----------+----------+---------
NL_ID | bigint | | not null |
EVENT_ID | bigint | | not null |
EVENT_TIME | integer | | not null |
EVENT_TYPE | character varying(32) | | not null |
CAT_NAME | character varying(256) | | |
DB_NAME | character varying(128) | | |
TBL_NAME | character varying(256) | | |
MESSAGE | text | | |
MESSAGE_FORMAT | character varying(16) | | |{noformat}
Fields like client address, client id (customized) will be helpful. HMS clients
can set their client id, e.g. Impala's catalog_service_id, when calling HMS
RPCs.
