  Used for partition table scan

• string log_id = 8

• int64 tp = 2

• bytes data = 3

• uint64 start_ts = 7

• repeated KeyRange ranges = 4

• bool is_cache_enabled = 5

  If cache is enabled, TiKV returns cache hit instead of data if its last version matches this `cache_if_match_version`.

• uint64 cache_if_match_version = 6

• int64 schema_ver = 8

  Any schema-ful storage to validate schema correctness if necessary.

• bool is_trace_enabled = 9

• uint64 paging_size = 10

  paging_size is 0 when it's disabled, otherwise, it should be a positive number.

• repeated StoreBatchTask tasks = 11

  tasks stores the batched coprocessor tasks sent to the same tikv store.

• uint64 connection_id = 12

  This is the session id between a client and tidb

• string connection_alias = 13

  This is the session alias between a client and tidb

• optional kvrpcpb.LockInfo locked = 3

• string other_error = 4

• optional KeyRange range = 5

• optional kvrpcpb.ExecDetails exec_details = 6

  This field is always filled for compatibility consideration. However newer TiDB should respect `exec_details_v2` field instead.

• optional kvrpcpb.ExecDetailsV2 exec_details_v2 = 11

  This field is provided in later versions, containing more detailed information.

• bool is_cache_hit = 7

• uint64 cache_last_version = 8

• bool can_be_cached = 9

• uint64 latest_buckets_version = 12

  Contains the latest buckets version of the region. Clients should query PD to update buckets in cache if its is stale.

• repeated StoreBatchTaskResponse batch_responses = 13

  StoreBatchTaskResponse is the collection of batch task responses.
