Setting index.codec to best_compression affects ElasticSearch’s or Graylog’s performance?


(Santhosh Sabarish KM) #1

We are using ElasticSearch, Graylog, and MongoDB for storing the application logs. The disk space utilization is growing day by day, although we use a retention mechanism we need to reduce it further. Will compressing the indices affect the performance of ElasticSearch or Graylog?
Does the compression happen in the background or the main thread? Will it cause more latency on the client side (Graylog sidecar collector, GELF, etc)?
