-----------------------------------------
Summary: Add test coverage for native format job upgrades
Key: FLINK-26002
URL: https://issues.apache.org/jira/browse/FLINK-26002
Project: Flink
Issue Type: Improvement
Components: Runtime / Checkpointing
Affects Versions: 1.15.0
Reporter: Anton Kalashnikov
Assignee: Anton Kalashnikov
Fix For: 1.15.0
# Initialization of job with an operator with states.
# Do native savepoint/canonical savepoint/aligned checkpoint
## Change job shape(new custom operator) and/or record types
## One job, with all possible network exchanges (forward, keyBy, rebalance,
broadcast, random, rescale), followed by stateful operator.
## No need to modify state schema. Just validate in some way that after upgrade
state is assigned to correct operators (so the state should be affecting result
of the operators/functions)
## Some record type that would allow us to validate consistency of the
computations
## Validating sink, checking for the consistency
## Arbitrary job upgrade. Add two new operators. A chained mapping operator and
a another keyed proceeded by keyed exchange . Change record type from int to
string, without changing the “logical” value of the record (for example change
1 → "1")
## Job upgrade w/o changing the graph record type: no need to test for that
# Restore from savepoint/checkpoint
