Eugene Koifman commented on HIVE-20607: --------------------------------------- Most of the statements are executed once per DB txn. What does this change solve? > TxnHandler should use PreparedStatement to execute direct SQL queries. > ---------------------------------------------------------------------- > > Key: HIVE-20607 > URL: https://issues.apache.org/jira/browse/HIVE-20607 > Project: Hive > Issue Type: Bug > Components: Standalone Metastore, Transactions > Affects Versions: 4.0.0 > Reporter: Sankar Hariappan > Assignee: Sankar Hariappan > Priority: Major > Labels: ACID > Fix For: 4.0.0 > > > TxnHandler uses direct SQL queries to operate on Txn related databases/tables > in Hive metastore RDBMS. > Most of the methods are direct calls from Metastore api which should be > directly append input string arguments to the SQL string. > Need to use parameterised PreparedStatement object to set these arguments. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
