Data caching multiplying memory requirements of Hot Rod server

    XMLWordPrintable

Details

    Description

      After inserting a 160MB object in Hot Rod, the memory consumption of the server goes through the roof. The screenshot shows a couple of interesting things:

      1. Both the HotRodDecoder and the DataContainer have a byte[] of approx 160mb each. So, it seems like it's actually two copies of the same byte[]. It's clear though that only the cache container should have it, and any cache decoder data should be cleared when the request is completed.

      2. Netty's UnsafeDynamicChannelBuffer is still holding to a byte[] of 268MB approx. Judging by the 2nd screenshot attached, this appears to be belonging to the underlying ReplayingDecoder. That should also, if possible, be cleared up. I'll have a look around in the Netty code and maybe ping Trustin.
