---------------------------------
Summary: Precompile statements where needed across TxnHandler
Key: HIVE-23297
URL: https://issues.apache.org/jira/browse/HIVE-23297
Project: Hive
Issue Type: Improvement
Reporter: Marton Bod
Assignee: Marton Bod
There are multiple places in TxnHandler that could benefit from pre-compiling
sql queries using prepared statements. Some queries are complex in structure
(e.g. checkLock) and we use string concats to recreate them every time the
query is to run, in addition to re-parsing the query structure as well.
