-------------------------------------------
Summary: Use of SimpleDateFormat in RocksDBWindowStore may not be
Threadsafe
Key: KAFKA-6066
URL: https://issues.apache.org/jira/browse/KAFKA-6066
Project: Kafka
Issue Type: Bug
Components: streams
Reporter: Srikanth Sundarrajan
Priority: Minor
Currently SimpleDateFormat is used to construct segmentId from segmentName and
vice-versa. This however may not be thread safe if WindowStore is accessed by
more than one SteamTask/thread concurrently.
