|
# A typical RocksDB options file has three sections, which are
|
||
|
|
# Version, DBOptions, and more than one CFOptions. 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.
|
||
|
|
# * Section
|
||
|
|
# 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.
|
||
|
|
#
|
||
|
|
# Below is an example of a RocksDB options file:
|
||
|
|
[Version]
|
||
|
|
# The Version section stores the version information about rocksdb
|
||
|
|
# and option file. This is used for handling potential format
|
||
|
|
# change in the future.
|
||
|

options_file_version=1.0
|
||
|
|
[DBOptions]
|
||
|
|
# Followed by the Version section is the DBOptions section.
|
||
|
|
# The value of an options can be assigned using a statement.
|
||
|
|
# Note that for those options that is not set in the options file,
|
||
|
|
# we will use the default value.

[CFOptions "default"]
|
||
|
|
# ColumnFamilyOptions section must follow the format of
|

# [CFOptions "cf name"]. If a rocksdb instance
|

|
|
# has multiple column families, then its CFOptions must be

[CFOptions "the second column family"]

|
# default value.
