Hello Lars Volker, I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/8436 to look at the new patch set (#3). Change subject: IMPALA-6054: Parquet dictionary pages should be freed on dictionary construction ...................................................................... IMPALA-6054: Parquet dictionary pages should be freed on dictionary construction During dictionary constructon, most types are copied from the parquet dictionary page, but StringValues keep pointers to it. In this case, the dictionary page must be kept and attached to the last row batch that references it. In case of other types, it is safe do delete the dictionary page after the construction of the dictionary. This patch contains two optimizations: - dictionary pages are deleted as soon as possible for non string types - in non-compressed and non-string case, an unnecessary copy is avoided Change-Id: I4d9d5f4da1028d961155dafdac0028a1c3641004 --- M be/src/exec/parquet-column-readers.cc 1 file changed, 36 insertions(+), 18 deletions(-) git pull ssh://gerrit.cloudera.org:29418/Impala-ASF refs/changes/36/8436/3 -- To view, visit http://gerrit.cloudera.org:8080/8436 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: newpatchset Gerrit-Change-Id: I4d9d5f4da1028d961155dafdac0028a1c3641004 Gerrit-Change-Number: 8436 Gerrit-PatchSet: 3 Gerrit-Owner: Csaba Ringhofer <csringho...@cloudera.com> Gerrit-Reviewer: Csaba Ringhofer <csringho...@cloudera.com> Gerrit-Reviewer: Lars Volker <l...@cloudera.com>
