+## Deprecation
+
+As of June 2013 the Jena developers agreed to treat SDB as a deprecated component - see [Future

+The developers intend to continue releasing SDB alongside other Jena components but it is
not actively maintained since none of the developers are familiar with SDB or use it in their
organizations.
+
+SDB may be revived as a fully supported component if members of the community come forward
to maintain it.  The Jena team strongly recommends the use of [TDB](../tdb/) instead of SDB
for all new development due to TDBs substantially better performance and scalability.
