   I think it's not an obvious win though .. Zstd looks more for archiving purpose with less
throughput with high compression ratio vs lz4 is for more throughput with less compression.
   
   > The main purpose of event logs is archiving. Many logs are generated and occupy the
storage, but most of them are never accessed by users.
   
   But I tend to agree with this. cc @HeartSaVioR or @tgravescs too FYI in case you guys have
different thoughts on this.
