WAL reload

[Govind C]

The WAL got reloaded according to the logs as shown below

level=info ts=2021-04-24T20:39:54.943Z caller=head.go:768 component=tsdb msg="WAL segment loaded" segment=77100 maxSegment=77102

But I still see the WAL under the data folder, I thought that was supposed to be deleted?

-rw-r--r-- 1 pro pro 134119424 Apr 11 04:01 00070739

-rw-r--r-- 1 pro pro 132874240 Apr 11 04:04 00070740

-rw-r--r-- 1 pro pro 133693440 Apr 11 04:07 00070741

[ wal]$ ls -l | grep 000 |wc -l

6413

[ wal]$ ls | grep check

checkpoint.00070694

checkpoint.00070738.tmp

checkpoint.00074965.tmp

Does that mean. if I restart Prometheus again will these WALs get loaded?

Cheers
