-----------------------------------
Summary: Change table property key 'log.scan' to 'startup.mode'
and add a default startup mode in Table Store
Key: FLINK-30294
URL: https://issues.apache.org/jira/browse/FLINK-30294
Project: Flink
Issue Type: Improvement
Components: Table Store
Affects Versions: table-store-0.3.0
Reporter: Caizhi Weng
Assignee: Caizhi Weng
We're introducing time-travel reading of Table Store for batch jobs. However
this reading mode is quite similar to the "from-timestamp" startup mode for
streaming jobs, just that "from-timestamp" streaming jobs only consume
incremental data but not history data.
We can support startup mode for both batch and streaming jobs. For batch jobs,
"from-timestamp" startup mode will produce all records from the last snapshot
before the specified timestamp. For streaming jobs the behavior doesn't change.
Previously, in order to use "from-timestamp" startup mode, users will have to
specify "log.scan" and also "log.scan.timestamp-millis", which is a little
inconvenient. We can introduce a "default" startup mode and its behavior will
base on the execution environment and other configurations. In this way, to use
"from-timestamp" startup mode, it is enough for users to specify just
"startup.timestamp-millis".
