             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.
