# 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.
#
# Below is an example of a RocksDB options file:
