Pranay Singh has uploaded a new patch set (#2). Change subject: IMPALA-5522:Use tracked memory for DictDecoder and DictEncoder ......................................................................
IMPALA-5522:Use tracked memory for DictDecoder and DictEncoder Currently DictDecoder class and DictEncoder class uses std::vector to store the tables mapping codeword to value and vice-versa. It is hard to detect the memory usage by these tables when they becomes very large, since this memory is not accounted by Impala's memory mangement infrastructure. This patch uses existing dictionary_pool_ to track the memory used by std::vector in DictDecoder class, whereas an existing memory pool for DictEncoder class is used when allocating memory for std::vector in DictEncoder class.
