6 slapd\-wt \- WiredTiger backend to slapd
10 The \fBwt\fP backend to
12 uses WiredTiger database library to store data.
14 The \fBwt\fP backend is experimental module that have potential high
15 write performance and high concurrency performance.
16 This backend have not some basic feature yet. Please backup data using
17 slapcat before update the module.
22 options apply to the \fBwt\fP backend database.
23 That is, they must follow a "database wt" line and
24 come before any subsequent "backend" or "database" lines.
25 Other database options are described in the
29 .BI directory \ <directory>
30 Specify WiredTiger home directory that containing this database and
31 associated indexes live.
32 A separate directory must be specified for each database.
34 .BR LOCALSTATEDIR/openldap\-data .
36 \fBwtconfig \fR{\fBcreate\fR,\fBcache_size=512M\fR,\fBasync=(enabled)\fR}
37 Specify configuration for wiredtiger, This parameter is pass to
38 .BR wiredtiger_open (3).
42 create the database if it does not exist.
47 maximum heap memory to allocate for the cache.
52 asynchronous operations configuration options. disabled by default.
56 \fBindex \fR{\fI<attrlist>\fR|\fBdefault\fR} [\fBpres\fR,\fBeq\fR,\fBapprox\fR,\fBsub\fR,\fI<special>\fR]
57 Specify the indexes to maintain for the given attribute (or
59 Some attributes only support a subset of indexes.
60 If only an \fI<attr>\fP is given, the indices specified for \fBdefault\fR
62 Note that setting a default does not imply that all attributes will be
63 indexed. Also, for best performance, an
65 index should always be configured for the
72 backend honors access control semantics as indicated in
82 .BR slapd\-config (5),
87 WiredTiger documentation.
