NAME
       slapd-wt	- WiredTiger backend to	slapd

SYNOPSIS
       /usr/local/etc/openldap/slapd.conf

DESCRIPTION
       The  wt	backend	 to slapd(8) uses WiredTiger database library to store
       data.

       The wt backend is experimental module that have	potential  high	 write
       performance  and	 high  concurrency performance.	 This backend have not
       some basic feature yet. Please backup data using	slapcat	before	update
       the module.

CONFIGURATION
       These  slapd.conf  options  apply to the	wt backend database.  That is,
       they must follow	a "database wt"	line and come  before  any  subsequent
       "backend" or "database" lines.  Other database options are described in
       the slapd.conf(5) manual	page.

       directory _directory_
	      Specify WiredTiger home directory	that containing	this  database
	      and associated indexes live.  A separate directory must be spec-
	      ified for	each database.	The default is /var/db/openldap-data.

       idlcache	_boolean_
	      Use the in-memory	idlcache. The default is true.

       index {_attrlist_|default} [pres,eq,approx,sub,_special_]
	      Specify the indexes to maintain for the given attribute (or list
	      of  attributes).	 Some  attributes only support a subset	of in-
	      dexes.  If only an _attr_	is given, the  indices	specified  for
	      default  are  maintained.	  Note that setting a default does not
	      imply that all attributes	will be	indexed. Also, for  best  per-
	      formance,	 an  eq	 index should always be	configured for the ob-
	      jectClass	attribute.

       mode _integer_
	      back-wt does not support mode option. use	umask instead.

       wtconfig	{create,cache_size=512M,async=(enabled)}
	      Specify configuration for	wiredtiger, This parameter is pass  to
	      wiredtiger_open(3).

	      create create the	database if it does not	exist.

	      cache_size
		     maximum heap memory to allocate for the cache.

	      async  asynchronous  operations  configuration options. disabled
		     by	default.
