Julien Pivotto	ed623f69e2	tsdb: don't allow ingesting empty labelsets (#6891 ) * tsdb: don't allow ingesting empty labelsets When we ingest an empty labelset in the head, further blocks can not be compacted, with the error: ``` level=error ts=2020-02-27T21:26:58.379Z caller=db.go:659 component=tsdb msg="compaction failed" err="persist head block: write compaction: add series: out-of-order series added with label set \"{}\" / prev: \"{}\"" ``` We should therefore reject those invalid empty labelsets upfront. This can be reproduced with the following: ``` cat << END > prometheus.yml scrape_configs: - job_name: 'prometheus' scrape_interval: 1s basic_auth: username: test password: test metric_relabel_configs: - regex: ".*" action: labeldrop static_configs: - targets: - 127.0.1.1:9090 END ./prometheus --storage.tsdb.min-block-duration=1m ``` And wait a few minutes.
