When dumping data, this error is prompted. How can I solve it?
Although the data volume is large, I am only exporting a specific table with very little data. It shouldn’t be like this, right?
The export time is too long, and the data is being cleaned up by GC. Extend the GC time a bit:
set global tidb_gc_life_time=‘12h0m0s’;
After the export is complete, revert it to the previous value.
Before exporting a large amount of data, you need to set the global tidb_gc_life_time to avoid outdated snapshots.
