How Do I Clear the Buffer After a Cache Session Is Used to Avoid Memory Usage?

Default implementation. Each cache session occupies 512 KB.

Thanks for reporting this. The intention was that you'd just read from the stream, and it'd reset its buffer itself. The ChannelPipedInputStream does call ByteArrayBuffer.compact() when more than 32kb have been read, or when all available data has been read.

However: when all has been read, then ByteArrayBuffer.compact() does not resize the array but only resets the write and read positions. That's not good.

This will need to be fixed in ChannelPipedInputStream so that the buffer array is cleared on EOF, and is indeed re-set to some small size if all currently available data has been read.

Also: are you closing the input streams you're reading from when the commands are done? That should also remove the buffers.
