Hi,

that's probably caused by InMemPersistenceManager.init():

        /**
         * store BLOB data in local file system in a sub directory
         * of the workspace home directory
         */
        LocalFileSystem blobFS = new LocalFileSystem();
        blobFS.setRoot(new File(context.getHomeDir(), "blobs"));
        blobFS.init();
        this.blobFS = blobFS;
        blobStore = new FileSystemBLOBStore(blobFS);

I guess this could be changed into a BasedFileSystem. Can you please
create a JIRA issue? And of course a patch is welcome.... ;)

Hi all.

I'm using JR in-memory repository for unit tests
where i create some custom nodes which in turn contain binary images.

Is the correct behavior, that JR should hold its whole data,
inclusively the lucene index, and the created nodes and imported binary
files in memory?

If so, i have a different behavior than that:
JR generates among others the ./workspaces/default/blobs/ folder which
contains sub folders with binary images.

After shutting down the repository, these generated sub folders and files
are removed, thats OK.


How can i configure JR to hold all data in-memory?


Here my current configuration for unit tests:
