Describe the bug
Logs that have been ingested disappear after the chunks were removed from the
ingesters' memory. Before the chunks are flushed and removed, all of the logs
are queryable via logcli and Grafana.
Reproduced with commit hash fa79c2469c59c90cfb8e0415b0998665d5db2601
in single process mode, but also happened in microservice mode with S3-DynamoDB
and Cassandra-Cassandra index-chunk storage.
Please reopen. Affects versions 1.6.0 and 1.6.1 at least. I can read and write logs to Loki, but within a minute. Then they're lost.
Here is my /etc/loki/loki.yaml

) to tailrandom2.txt
{filename!=""}
, there are 450 log lines as expectedloki_ingester_memory_chunks
metric dropped to 0{filename!=""}
, there are less than 450 log lines. The remaining log lines are here.Expected behavior
The number of logs returned after the chunks are removed from memory to be equal
with when the logs haven't been flushed yet.
