RE: 30 secondes to create and open a repository ?

[Palmer, Tom]

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.
