# This is a RocksDB option file.
|
||
|
|
#
|
||
|
|
# A typical RocksDB options file has four sections, which are
|
||
|
|
# Version section, DBOptions section, at least one CFOptions
|
||
|
|
# section, and one TableOptions section for each column family.
|
||
|
|
# The RocksDB options file in general follows the basic INI
|
||
|
|
# file format with the following extensions / modifications:
|
||
|
|
#
|
||
|
|
# * Escaped characters
|
||
|
|
# We escaped the following characters:
|
||
|
|
# - \n -- line feed - new line
|
||
|
|
# - \r -- carriage return
|
||
|
|
# - \\ -- backslash \
|
||
|
|
# - \: -- colon symbol :
|
||
|
|
# - \# -- hash tag #
|
||
|
|
# * Comments
|
||
|
|
# We support # style comments. Comments can appear at the ending
|
||
|
|
# part of a line.
|
||
|
|
# * Statements
|
||
|
|
# A statement is of the form option_name = value.
|
||
|
|
# Each statement contains a '=', where extra white-spaces
|
||
|
|
# are supported. However, we don't support multi-lined statement.
|
||
|
|
# Furthermore, each line can only contain at most one statement.
|
||
|
|
# * Sections
|
||
|
|
# Sections are of the form [SecitonTitle "SectionArgument"],
|
||
|
|
# where section argument is optional.
|
||
|
|
# * List
|
||
|
|
# We use colon-separated string to represent a list.
|
||
|
|
# For instance, n1:n2:n3:n4 is a list containing four values.
|
||
|
|
#
