   Nice. When we had added support for ZSTD and LZ4 compression types in https://github.com/apache/pinot/issues/6804, our perf testing also had similar results. LZ4 gives nearly same (and even better sometimes) the compression ratio compared to SNAPPY but the time to compress is much faster. 
   
   ZSTD on the other hand as highest compression ratio (from our tests) but compression/decompression time was higher as well
   
   Here are the results for reference - https://docs.google.com/document/d/1ie4JmVofk2o6ryCX7T4aD7GsRPKS651mroXhDk41wys/edit
