Subject RE: 30 secondes to create and open a repository ?
Date Thu, 11 Nov 2010 13:59:16 GMT
If you're just doing unit testing, we've been very happy with an
in-memory repository.  It still needs some tmp directory setup/teardown
but a parent test case deals with that.  Here's our repository XML:

<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE Repository PUBLIC "-//The Apache Software Foundation//DTD
Jackrabbit 1.4//EN"
 
"http://jackrabbit.apache.org/dtd/repository-2.0.dtd">

<!-- Minimal memory-based JCR configuration file for unit testing -->
<Repository>

	<FileSystem
class="org.apache.jackrabbit.core.fs.mem.MemoryFileSystem"/>

	<Security appName="Jackrabbit">
		<AccessManager
class="org.apache.jackrabbit.core.security.simple.SimpleAccessManager"/>
		<LoginModule
class="org.apache.jackrabbit.core.security.simple.SimpleLoginModule">
			<param name="anonymousId" value="anonymous"/>
		</LoginModule>
	</Security>

	<Workspaces rootPath="${rep.home}/workspaces"
defaultWorkspace="draft"/>

	<Workspace name="${wsp.name}">
		<FileSystem
class="org.apache.jackrabbit.core.fs.mem.MemoryFileSystem"/>
		<PersistenceManager
class="org.apache.jackrabbit.core.persistence.mem.InMemPersistenceManage
r">
			<param name="persistent" value="false"/>
		</PersistenceManager>
		<SearchIndex
class="org.apache.jackrabbit.core.query.lucene.SearchIndex">
			<param name="path" value="${wsp.home}/index"/>
		</SearchIndex>
	</Workspace>

	<Versioning rootPath="${rep.home}/versions">
		<FileSystem
class="org.apache.jackrabbit.core.fs.mem.MemoryFileSystem"/>
		<PersistenceManager
class="org.apache.jackrabbit.core.persistence.mem.InMemPersistenceManage
r">
			<param name="persistent" value="false"/>
		</PersistenceManager>
	</Versioning>
	<SearchIndex
class="org.apache.jackrabbit.core.query.lucene.SearchIndex">
		<param name="path"
value="${rep.home}/repository/index"/>
	</SearchIndex>
</Repository>

Enjoy -

Try h2.  It is quite a bit faster to startup than Derby.  It also has
the benefit that a crash will usually not require manually deleting lock
files.
