NAME

       slapd-wt - WiredTiger backend to slapd

SYNOPSIS

       ETCDIR/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 specified for each database.  The
              default is LOCALSTATEDIR/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 indexes.  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 performance, an eq index should
              always be configured for the objectClass 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).
