Compress Files

HopFS supports erasure-coding of files, which reduces storage requirements for large files by roughly 50%. If a file consists of 6 file blocks or more (that is, if the file is larger than 384 MB in size, for a default block size of 64 MB), then it can be compressed. Smaller files cannot be compressed.

Option Description
