Running Loki in k8s, using loki-distributed helm chart.
Index is TSDB and using latest Loki version.
Was able to scale loki-distributed-querier by adding more machines and
BytesProcessedPerSecond upto 24GB (15 machines[16 core, 32Gb machines]).
But once we add more machines 20, or 25, won’t see much difference in performace?, is BytesProcessedPerSecond depends upon any specific setting apart from
thanks in advance.
There are several configurations that are related to parallelism. The one that’s directly related to querier is
split_queries_by_interval. It is possible that at some point you can have more queriers than split queries to run (from a testing perspective). There is also a storage configuration that sets a limit to maximum number of chunks that can be read at the same time.
24GB per second processed is pretty impressive.
Followed recomended settings mentioned in the webinar, Best practices for configuring Grafana Loki
