> The key in the map is `<regionId>:<tableId>`, I think we can encode regionId in wal directory path, so the key could only contains `tableId`. > Use the manifest file to skip logs that have already been deleted. How will you skip WAL files? Which strategy will you use? > Update the values in the map, create a new manifest file, and overwrite the old file. This is the normal case, what if there are some partials error, such as overwrite failed, you need to document more details, pseudo code or sequence diagram may help. > Record the maximum sequence number of all tables in each segment file in memory How will you recovery this info when server start up? do we need to iterate the whole WAL files? -- This is an automated message from the Apache Git Service.
