mtbl_info

MTBL_INFO(1)															      MTBL_INFO(1)

NAME

       mtbl_info - display information about an MTBL file

SYNOPSIS

       mtbl_info FILE [FILE]...

DESCRIPTION

       mtbl_info(1) displays the following information about the MTBL files specified on the command line.

       file name -- the name of the MTBL file.

       file size -- the total size of the MTBL file, in bytes.

       index bytes -- the total number of bytes and proportion of the total file size consumed by the index.

       data block bytes -- the total number of bytes and proportion of the total file size consumed by data blocks.

       data block size -- the maximum size of an uncompressed data block.

       data block count -- the total number of data blocks.

       entry count -- the total number of key-value entries.

       key bytes -- the total number of bytes that all keys in the file would occupy if stored end-to-end in a byte array with no delimiters.

       value bytes -- the total number of bytes that all values in the file would occupy if stored end-to-end in a byte array with no delimiters.

       compression algorithm -- the algorithm used to compress data blocks. Possible values are "none", "snappy" and "zlib".

       compactness -- a rough metric comparing the total number of bytes in the key-value entries with the total size of the MTBL file. It is
       calculated as (file size) / (key bytes + value bytes), and thus takes into account the gains of data block compression and prefix key
       compression against the overhead of the index, trailer, and data block offset arrays.
