Posted by ba...@apache.org.
This is an automated email from the ASF dual-hosted git repository.
baunsgaard pushed a commit to branch main
in repository https://gitbox.apache.org/repos/asf/systemds.git
commit 31f2653b785c4e00c987347264f5f96e8315dd4c
Author: Muhammad Osama <mu...@student.tugraz.at>

[SYSTEMDS-2831] CLA DeltaDDC Column Group
This commit adds a new column group type named DeltaDDC, with support for
a few operations.
While merging I added a interface for future readers for delta encoding,
a future tasks is to enable analysis of delta encoding.
DIA project WS2021/22.
Closes #1518
