Description

importer read all the files in concurrent, it would cause below issues:

  1. if there're 1000+ files, it would read too many data, and would OOM.
  2. one goroutine reads one file, if there is only one file, would import slow even if there're many graph clients.

Contributor guide

Research direction
Identify the root cause of OOM and single file slowness in the concurrent file reader. Consider implementing a semaphore or worker pool to limit the number of goroutines reading files simultaneously.
