Multi-Shard Query, Data Loading, and DML Enhancements

If any shards are unavailable during query execution, then the enhanced multi-shard query attempts to find alternate shards to operate on, and the query resumes without issuing a failure condition. Bulk data loading and DML can operate on multiple shards simultaneously.

Multi-shard queries are more fault-tolerant. Bulk data loading and DML operations can occur across all shards simultaneously, making these operations much faster.
