Onder Kalaci	6c7abc2ba5	Add fast shard pruning path for INSERTs on hash partitioned tables ... This commit adds a fast shard pruning path for INSERTs on hash-partitioned tables. The rationale behind this change is that if there exists a sorted shard interval array, a single index lookup on the array allows us to find the corresponding shard interval. As mentioned above, we need a sorted (wrt shardminvalue) shard interval array. Thus, this commit updates shardIntervalArray to sortedShardIntervalArray in the metadata cache. Then uses the low-level API that is defined in multi_copy to handle the fast shard pruning. The performance impact of this change is more apparent as more shards exist for a distributed table. Previous implementation was relying on linear search through the shard intervals. However, this commit relies on constant lookup time on shard interval array. Thus, the shard pruning becomes less dependent on the shard count.	2016-04-26 11:16:00 +03:00
