Summary: Optimize History GC for Compliance Oriented Use Cases
Key: KUDU-1431
URL: https://issues.apache.org/jira/browse/KUDU-1431
Project: Kudu
Issue Type: Improvement
Reporter: Jordan Birdsell
Many compliance based use cases require prompt removal of select data from
disk, including all history. In practice this can require both row deletes and
erasing or masking of data within a column.
The initial version of tablet history GC being worked on in KUDU-236 will not
be able to support the SLA of such compliance oriented use cases. This request
is to address improving the ability of tablet history GC to accommodate these
types of deletes within a very short period of time (1-3 days). Ideally this
could be configured on a transaction level, since not all record updates on a
table are for compliance reasons.
