> - Created extra (db, tbl, part) index on HIVE_LOCKS table;
> - Replaced inner select under checkLocks using multiple IN statements with
> JOIN operator;
> generated query looks like :
> {code}
> SELECT LS.* FROM (
> SELECT HL_LOCK_EXT_ID, HL_DB, HL_TABLE, HL_PARTITION, HL_LOCK_STATE,
> HL_LOCK_TYPE FROM HIVE_LOCKS
> WHERE HL_LOCK_EXT_ID < 333) LS
> INNER JOIN (
> SELECT HL_DB, HL_TABLE, HL_PARTITION, HL_LOCK_TYPE FROM HIVE_LOCKS WHERE
> HL_LOCK_EXT_ID = 333) LBC
> ON LS.HL_DB = LBC.HL_DB
> AND (LS.HL_TABLE IS NULL OR LBC.HL_TABLE IS NULL OR LS.HL_TABLE =
> LBC.HL_TABLE
> AND (LS.HL_PARTITION IS NULL OR LBC.HL_PARTITION IS NULL OR
> LS.HL_PARTITION = LBC.HL_PARTITION))
> WHERE (LBC.HL_TXNID = 0 OR LS.HL_TXNID != LBC.HL_TXNID)
> AND (LBC.HL_LOCK_TYPE='e'
> AND !(LS.HL_TABLE IS NULL AND LS.HL_LOCK_TYPE='r' AND LBC.HL_TABLE
> IS NOT NULL )
> OR LBC.HL_LOCK_TYPE='w' AND LS.HL_LOCK_TYPE IN ('w','e')
> OR LBC.HL_LOCK_TYPE='r' AND LS.HL_LOCK_TYPE='e'
> AND !(LS.HL_TABLE IS NOT NULL AND LBC.HL_TABLE IS NULL))
> LIMIT 1;
> {code}
