PARQUET-1032: fix varint-encode() encoding algorithm link The spec says that varint-encode() is ULEB-128 encoding but links to VLQ algorithm that is slightly different from ULEB-128. Author: kostya-sh <kostya...@users.noreply.github.com> Closes #69 from kostya-sh/patch-1 and squashes the following commits: f128603 [kostya-sh] PARQUET-1032: fix varint-encode() encoding algorithm link Project: http://git-wip-us.apache.org/repos/asf/parquet-format/repo Commit: http://git-wip-us.apache.org/repos/asf/parquet-format/commit/499d5971 Tree: http://git-wip-us.apache.org/repos/asf/parquet-format/tree/499d5971 Diff: http://git-wip-us.apache.org/repos/asf/parquet-format/diff/499d5971 Branch: refs/heads/master Commit: 499d597106e9ff68b802f1a68ea70c9df55c68d7 Parents: 7923dc6 Author: kostya-sh <kostya...@users.noreply.github.com> Authored: Fri Oct 6 16:21:49 2017 -0700 Committer: Ryan Blue <b...@apache.org> Committed: Fri Oct 6 16:21:49 2017 -0700 ---------------------------------------------------------------------- Encodings.md | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) ---------------------------------------------------------------------- http://git-wip-us.apache.org/repos/asf/parquet-format/blob/499d5971/Encodings.md ---------------------------------------------------------------------- diff --git a/Encodings.md b/Encodings.md index c4cdf70..7cf880e 100644 --- a/Encodings.md +++ b/Encodings.md @@ -101,7 +101,7 @@ repeated-value := value that is repeated, using a fixed-width of round-up-to-nex shifting and ORing with a mask.
