Hi all, Memory mode of ES seems to default to direct byte buffers using ByteBufferDirectory. I understand that this is still fresh functionality (not part of main Lucene release yet), has anyone run in this mode in production for a extended period of time?

Anyone? I'm just trying to find if there are any specific issues I need to be mindful of when using this mode. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
