------------------------------
Summary: Handle replication bootstrap of large databases
Key: HIVE-16865
URL: https://issues.apache.org/jira/browse/HIVE-16865
Project: Hive
Issue Type: Improvement
Components: HiveServer2
Affects Versions: 3.0.0
Reporter: anishek
Assignee: anishek
Fix For: 3.0.0
for larger databases make sure that we can handle replication bootstrap.
* Assuming large database can have close to million tables or a few tables with
few hundred thousand partitions.
* for function replication if a primary warehouse has large number of custom
functions defined such that the same binary file in corporates most of these
functions then on the replica warehouse there might be a problem in loading all
these functions as we will have the same jar on primary copied over for each
function such that each function will have a local copy of the jar, loading all
these jars might lead to excessive memory usage.
