+###### JDBM2 Store
+
+The JDBM2 store implementation is redistributable by apache so it can 
+be used out of the box without having to install any additional software.
+The problem with this store is that it's single threaded in nature and
+subsequently has several unwanted performance problems.  For example,
+the store periodically will compact itself to reclaim disk space but
+the compaction is a slow process which pauses access to the store while 
+the compaction is running. 
+
+You can enable the store by adding a `jdbm2_store` element
+inside your `virtual_host`.  Example:
+    
+{pygmentize:: xml}
+  ...
+  <virtual_host id="default">
+    ...
+    <jdbm2_store directory="${apollo.base}/data"/>
+    ..
+  </virtual_host>
+  ...
+{pygmentize}
+
+A `jdbm2_store` element may be configured with the following attributes:
+
+* `directory` : The directory which the store will use to hold it's data
+  files. The store will create the directory if it does not already
+  exist.
+* `flush_delay` : The flush delay is the amount of time in milliseconds
+  that a store will delay persisting a messaging unit of work in hopes
+  that it will be invalidated shortly thereafter by another unit of work
+  which would negate the operation.
+* `compact_interval` : how often the store is compacted in seconds.  If 
+  this attribute is not set, it will default to 60 seconds. Set to -1 
+  to disable compaction altogether.
+
