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.

ACCESS CONTROL
       The  wt	backend	 honors	 access	 control  semantics  as	 indicated  in
       slapd.access(5).

FILES
