This turned out to be a good advice. I am evaluating if it is possible to somehow intelligently sample the data when it comes to ELK. Something like an average of 1min data via a logstash filter. We could do this from our backend programs too, but for now, I am trying to do this in ELK during the writes.
Also we do not use Clickhouse, but I will see if I can somehow do a sampling rate in the reads, during my read queries. Thanks.
