ASF subversion and git services commented on IMPALA-5843: --------------------------------------------------------- Commit 969dea84f41cfccf863b14904958a5d2be91983f in impala's branch refs/heads/master from Zoltan Borok-Nagy [ https://gitbox.apache.org/repos/asf?p=impala.git;h=969dea8 ] IMPALA-7979: Enhance decoders to support value-skipping This commit adds value-skipping functionality to the decoders. Value-skipping is useful when we know that we won't need the following N values, so instead of decoding and dropping them, we can just "jump" through them. This feature is a prerequisite for Parquet page skipping (IMPALA-5843). I added backend tests for all the decoders. Backed tests related to bitpacking are moved to the newly created bit-stream-utils-test.
