I will be co-presenting a talk at the MySQL Conference on Thursday April 23 in
Santa Clara, California on the back-ndb backend in OpenLDAP. Johan Andersson
from Sun/MySQL will also be presenting; Symas and MySQL worked together to
design the data model for this backend.
back-ndb is a new OpenLDAP slapd backend that provides direct access to
MySQL's NDB Cluster engine. The NDB Cluster design allows concurrent access to
relational tables from multiple access methods (including mysqld for
traditional SQL access, and slapd for LDAP access) and allows capacity to
scale horizontally across multiple data nodes. The OpenLDAP backend uses the
native NDBAPI to achieve high speed access without any SQL translation
overhead. Multiple slapd servers can operate concurrently on an NDB database,
along with other mysqld servers and other agents, allowing performance to be
augmented linearly simply by adding more nodes to a cluster.
This will be slightly more in-depth than the back-ndb talk I presented at the
UKUUG conference in March.
