Your no longer limited to running an embedded Cassandra server within Virgil. Get the same GUI, SOLR integration, and REST layer running against an existing cluster.
Since Virgil was originally developed as an embedded REST layer for the Cassandra Server, it ran as a daemon inside the server and performed operations directly against the CassandraServer classes. Running in a single JVM had some performance gains over a separate server that communicated over Thrift (either directly or via Hector) since operations didn't have to take a second hop across the network (with the associated marshalling/unmarshalling)
We had a request come in to add the ability to run Virgil against a remote Cassandra:
That seemed reasonable since there are a lot of existing cassandra clusters and users may just want to add a REST layer to support webapp/gui access
or SOLR integration
To support those cases, we added run-modes to the configuration:
Let us know what you think.
