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.
