Our internal benchmarks show slowdowns even as we increase the threshold here, although we can nearly recover (-9% QPS) the previous query-time performance disabling below 128 bytes. I'm beginning to wonder what the case is for compressing BDV at all? Do we see large BinaryDocValues fields that are not, or only rarely, decoded at query time? I think if such fields participate in the search in any significant way (ie for all hits), we are going to see these slowdowns. Maybe the bytes threshold is really just a proxy for binary doc values used as stored fields? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
