       slapd-wt - WiredTiger backend to slapd

SYNOPSIS         top


DESCRIPTION         top

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

       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.


       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

       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.

                     maximum heap memory to allocate for the cache.

              async  asynchronous operations configuration options. disabled
                     by default.

              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.
