So it is possible that this compression is already supported. Not sure about the full list of codecs, but I think it may be extended by specifying additional codecs in {{io.compression.codecs}} in hadoop conf file (perhaps in {{core-site.xml}}). was (Author: vvysotskyi): Please see examples of usage of querying compressed files here: [https://drill.apache.org/docs/querying-plain-text-files/#querying-compressed-files]. {{hadoop-common}} already contains lz4 compressors/decompressors.
