Performance boost for #elasticsearch: LogsDB with LZ4 Compression = storage savings and fast query times

WHAT LogsDB with LZ4 compression outperforms both standard index mode and LogsDB with DEFLATE for query speed with almost no downside.

WHY 30% improvement in query performance over LogsDB with DEFLATE. Minimal impact on compression efficiency (less than 1% loss). Balances fast queries with storage savings.

RESULTS LogsDB + LZ4: 1.179 seconds avg. query latency Standard mode + (DEFLATE): 1.448 seconds avg. query latency LogsDB + DEFLATE: 1.544 seconds avg. query latency

TLDR: Consider using "index.codec: default" when enabling Elasticsearch's LogsDB. It likely offers query performance advantages while still achieving 99% of the storage savings compared to data stored in a non-LogsDB index.

For those inquiring about the CPU utilization impact of enabling Elasticsearch's new LogsDB, as I mentioned in my previous post and as confirmed by the results below, I conducted a test processing approximately 18,000 firewall logs per second. The results are in: the CPU overhead for enabling LogsDB is minimal.

By leveraging the ~10% CPU efficiency improvement introduced in Elasticsearch 8.8, the cost becomes even less significant.

In short, enabling LogsDB is a smart choice—practically a no-brainer.
