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. 05/29/2012 MTBL_INFO(1)
