Content-Type: text/plain Message-Id: <20180412190307.B669BE0904@git1-us-west.apache.org> Date: Thu, 12 Apr 2018 19:03:07 +0000 (UTC) Github user wgtmac commented on the issue: https://github.com/apache/orc/pull/245 After second thought, I added back DECIMAL_V1 to support RLE v1 in decimal encoding. The reason is that in our testing, we found RLEv1 + zstd may be the best combination than others in terms of both compression ration and encoding/decoding speed. ---
