Parse whitespace-delimited (spaces or tabs) file (much faster than using a regular expression) • compression: decompress ’gzip’ and ’bz2’ formats on the fly. • dialect: string or csv.Dialect instance to (see below). 18.7.14 Compression PyTables allows the stored data to be compressed. Tthis applies to all kinds of stores, not just tables. • Pass complevel=int for a compression level (1-9, with 0 being being no compression, and the default) • Pass complib=lib where lib is any of zlib, bzip2, lzo, blosc for whichever compression library you prefer. HDFStore will use the file based compression scheme if
