raft entry is too large, region 2, entry size 12014018

[bxq2011hust]

Write ut in rust client, put 10240 kv pairs in one txn, the value is random bytes and length is 10240, the key is format!("key_________________________{}", j) which j is index in 0..10240, commit the txn failed. the error message is

Error: RegionError(Error { message: "raft entry is too large, region 2, entry size 12014018", not_leader: None, region_not_found: None, key_not_in_region: None, epoch_not_match: None, server_is_busy: None, stale_command: None, store_not_match: None, raft_entry_too_large: Some(RaftEntryTooLarge { region_id: 2, entry_size: 12014018 }), max_timestamp_not_synced: None, read_index_not_ready: None, proposal_in_merging_mode: None, data_is_not_ready: None, region_not_initialized: None, disk_full: None })

I run the same ut in c-client, it works fine, I guess the reason is rust client does not split kv pairs into batches in the same region?

Yes. It should be improved.
