Na Li commented on SENTRY-2024: ------------------------------- I am OK to drop this index, so we don't have issue for MySql server. I will attach a patch for review > Specify Char Set for AUTHZ_OBJ_NAME > ----------------------------------- > > Key: SENTRY-2024 > URL: https://issues.apache.org/jira/browse/SENTRY-2024 > Project: Sentry > Issue Type: Bug > Components: Sentry > Affects Versions: 2.0.0 > Reporter: Na Li > Assignee: Na Li > Priority: Critical > Attachments: SENTRY-2024.001.patch, SENTRY-2024.001.patch, > SENTRY-2024.001.patch, SENTRY-2024.002.patch, SENTRY-2024.002.patch > > > AUTHZ_OBJ_NAME has (384) chars. It is constructed by sentry from notification > event as {color:red}DB_NAME + "." + TBL_NAME{color}. To be consistent with > hive, sentry should use the same char set as what's used by DB_NAME and > TBL_NAME > Besides, if its table char set is utf8, the constrain AUTHZOBJNAME will have > error "Specified key was too long; max key length is 767 bytes" for mysql. > The solution is to specify the char set for this field, so it works for mysql > regardless the char set of its table or DB. > Reference: > 1) CREATE TABLE AUTHZ_PATHS_MAPPING > ( > AUTHZ_OBJ_ID BIGINT NOT NULL generated always as identity (start with 1), > AUTHZ_OBJ_NAME VARCHAR({color:red}384{color}), > CREATE_TIME_MS BIGINT NOT NULL > ); > CREATE UNIQUE INDEX AUTHZOBJNAME ON AUTHZ_PATHS_MAPPING > ({color:red}AUTHZ_OBJ_NAME{color}); > 2) AUTHZ_OBJ_NAME is constructed by sentry from notification event as > DB_NAME + "." + TBL_NAME.
