How about removing the “sql” at the end of the source directory? /hd*** like this?
When TiDB Lightning processes SQL files, it cannot quickly split a single file, so the import speed of a single file cannot be improved by increasing concurrency. Therefore, when exporting data to SQL files, it is advisable to avoid having a single SQL file that is too large. Typically, a single file around 256MiB can achieve optimal performance.
I changed the path a bit. This can only keep the directory path, not the file path.
I followed the official documentation to install Lightning, using tiup directly.
Is it looking for the file to be imported from the specified directory?
Yes, just like mydumper, you can specify the folder name. The export will also generate a folder containing the split SQL files.
