Could you please explain the general I/O model of TiDB? For example, when MySQL flushes dirty pages, it randomly writes 16KB of dirty pages. I would like to know what the I/O model of TiDB’s RocksDB is like when reading and writing. For instance, how much data is written to the disk each time when writing data from memory to disk?
