Sergey Shelukhin updated HIVE-5951:
-----------------------------------
Attachment: HIVE-5951.07.patch
Update some tests; rename method in thrift better (in other JIRA I am adding
more methods with request-response pattern, probably a good idea to call them
all ..._req rather than ...2).
> improve performance of adding partitions from client

> Adding partitions to metastore is currently very inefficient. There are small
> things like, for !ifNotExists case, DDLSemanticAnalyzer gets the full
> partition object for every spec (which is a network call to metastore), and
> then discards it instantly; there's also general problem that too much
> processing is done on client side. DDLSA should analyze the query and make
> one call to metastore (or maybe a set of batched calls if there are too many
> partitions in the command), metastore should then figure out stuff and insert
> in batch.
