SYNOPSIS

DESCRIPTION

12       The  wt  backend  to slapd(8) uses WiredTiger database library to store
13       data.
14
15       The wt backend is experimental module that have  potential  high  write
16       performance  and  high  concurrency performance.  This backend have not
17       some basic feature yet. Please backup data using slapcat before  update

CONFIGURATION

22       These  slapd.conf  options  apply to the wt backend database.  That is,
23       they must follow a "database wt" line and come  before  any  subsequent
24       "backend" or "database" lines.  Other database options are described in
25       the slapd.conf(5) manual page.
26
27       directory <directory>
28              Specify WiredTiger home directory that containing this  database
29              and associated indexes live.  A separate directory must be spec‐
30              ified for each database.  The default is /var/openldap-data.
31
32       idlcache <boolean>
33              Use the in-memory idlcache. The default is true.
34
35       index {<attrlist>|default} [pres,eq,approx,sub,<special>]
36              Specify the indexes to maintain for the given attribute (or list
37              of  attributes).   Some  attributes only support a subset of in‐
38              dexes.  If only an <attr> is given, the  indices  specified  for
39              default  are  maintained.   Note that setting a default does not
40              imply that all attributes will be indexed. Also, for  best  per‐
41              formance,  an  eq  index should always be configured for the ob‐
42              jectClass attribute.
43
44       mode <integer>
45              back-wt does not support mode option. use umask instead.
46
47       wtconfig {create,cache_size=512M,async=(enabled)}
48              Specify configuration for wiredtiger, This parameter is pass  to
49              wiredtiger_open(3).

52
53              cache_size
54                     maximum heap memory to allocate for the cache.
