Jaanai created PHOENIX-5055:
-------------------------------
Summary: Split the list of mutations into multiple batches
probably cause correctness of index data
Key: PHOENIX-5055
URL: https://issues.apache.org/jira/browse/PHOENIX-5055
Project: Phoenix
Issue Type: Bug
Affects Versions: 4.14.1, 5.0.0
Reporter: Jaanai
Assignee: Jaanai
Fix For: 5.1.0
In order to get more performance, we split the list of mutations into multiple
batches in MutationSate. For one upsert SQL with some null values that will
produce two type KeyValues(Put and DeleteColumn), These KeyValues should have
the same timestamp so that keep on an atomic operation for corresponding the
row key.
Found incorrect indexed data for the index tables by sqlline.

Dump ==================
{code}
The DeleteColumn's timestamp larger than other mutations.
