When updating partition metadata as part of COMPUTE STATS we would previously attempt to update all partitions at once. This could lead to HMS socket timeouts and also could run into issues if there were > 32K partitions. In this change we now update the partitions in batches, with a max size of 500 partitions per batch. We also compare whether the row count has changed and only update partitions that have been modified.
