> 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.
