Change subject: IMPALA-9389: [DOCS] Support reading zstd text files ...................................................................... Patch Set 4: (1 comment) http://gerrit.cloudera.org:8080/#/c/15304/3/docs/topics/impala_txtfile.xml File docs/topics/impala_txtfile.xml: http://gerrit.cloudera.org:8080/#/c/15304/3/docs/topics/impala_txtfile.xml@650 PS3, Line 650: capability. Impala can read compressed text files written by Hive or compressed by the > I did some experimentation and while Impala can read text files compressed Yes, I agree, we don't have to include "streaming" or "block". From user point, I think it only matters what source of compressed file impala can read, so for text, impala can read Hive compressed zstd file and standard library compressed zstd file. For standard library compressed file testing, we only have zstd for text. For hive compressed file testing, we have coverage for all codec. So we can say all hive written codec text, impala can read. But for standard library, we only verified zstd. -- To view, visit http://gerrit.cloudera.org:8080/15304 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: Ic83137bd2c3a49398fb60cf1901f8b74ed111fce Gerrit-Change-Number: 15304 Gerrit-PatchSet: 4 Gerrit-Owner: Anonymous Coward <[email protected]> Gerrit-Reviewer: Abhishek Rawat <[email protected]> Gerrit-Reviewer: Andrew Sherman <[email protected]> Gerrit-Reviewer: Impala Public Jenkins <[email protected]> Gerrit-Reviewer: Xiaomeng Zhang <[email protected]> Gerrit-Comment-Date: Fri, 28 Feb 2020 18:51:18 +0000 Gerrit-HasComments: Yes
