-------------------------------------
Summary: During bootstrap streaming, skipping write path may
create orphan MV rows
Key: CASSANDRA-16174
URL: https://issues.apache.org/jira/browse/CASSANDRA-16174
Project: Cassandra
Issue Type: Bug
Components: Feature/Materialized Views
Reporter: Zhao Yang
CASSANDRA-13065 improves the speed of bootstrap streaming by skipping write
path for base table with MV.
Unfortunately during bootstrapping, the bootstrapping node may receive a base
write that is already deleted or shadowed on other replicas, but the
bootstrapping node didn't receive all sstables yet thus bootstapping node may
create an orphan view row based on received sstables. Without write path, the
newer version data will not create tombstone to shadow orphan view row.
For example, node-A has a base sstable containing: "k=1, v=1@2019", but
bootstrapping node didn't receive it yet. A write "k=1, v=0@2018" hitting on
bootstrapping node will create an orphan view row: "v=0@2018, k=1". Applying
streaming sstables from bootstrap or rebuild through write path can help, but
that's something we want to get rid of.
