2 rocksdb kv 分离的优化，减少 Compaction 过程中对 blob 文件的随机 IO。

这个工作暂不推进，防止已经开启 blob 的 RocksDB 数据无法向前兼容。

2 Optimization of rocksdb kv separation to reduce random IO to blob files during the compaction process.

This work is not being advanced for the time being to prevent RocksDB data that has blobs enabled from being forward-compatible.

@AlexStocks the old pika is holding back a lot of new developments. possible to do an X version without considering the current technical debt?

1. doesnt need forward compatibility.
2. when performing slot migrate in future can have the X version immediately.
