PROGRAM:
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", "zlib", "lz4", and "lz4hc".
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, metadata, and data block offset arrays.
