########## File path: docs/release-notes/flink-1.10.md ########## @@ -468,3 +468,9 @@ deprecated in favor of `RocksDBOptionsFactory` and #### Incompatibility of serialized JobGraphs ([FLINK-14594](https://issues.apache.org/jira/browse/FLINK-14594)) Serialized `JobGraphs` which set the `ResourceSpec` created by Flink versions < `1.10` are no longer compatible with Flink >= `1.10`. If you want to migrate these jobs to Flink >= `1.10` you will have to stop the job with a savepoint and then resume it from this savepoint on the Flink >= `1.10` cluster. + +#### Disabled chaining of file reading through ContinuousFileReaderOperator (1.10.3). + +Any `readFile` or `readTextFile` of `DataStream` creates a `ContinuousFileReaderOperator` that used to be chained to subsequent operators. +However, chained operator do not trigger processing time timers correctly, leading to bugs in watermark assigners (FLINK-19109). As a workaround, +chaining of `ContinuousFileReaderOperator` is disabled. Flink 1.11.1 and later fixes the underlying problem and re-allows chaining.
