The cluster IO bottleneck is too large, I want to try TiDB Lightning to see if it can solve it.

Are you referring to disk I/O? Building a new setup and distributing it?

Are you talking about hotspot issues or something else?

  1. Is it the IO bottleneck of Lightning or the IO bottleneck of the cluster? Or do you have an IO bottleneck when using other import tools?
  2. Importing through Lightning with tidb-backend still requires the IO capability of the cluster; whereas importing through local-backend requires ensuring that the instance where Lightning is located has sufficient disk space, memory, and IO capability.
