------------------------------------
Summary: Check against negative timestamps
Key: KAFKA-3716
URL: https://issues.apache.org/jira/browse/KAFKA-3716
Project: Kafka
Issue Type: Bug
Components: streams
Reporter: Guozhang Wang
Assignee: Guozhang Wang
Although currently we do not enforce any semantic meaning on the {{Long}} typed
timestamps, we are actually assuming it to be non-negative while storing the
timestamp in windowed store. For example, in {{RocksDBWindowStore}} we store
the timestamp as part of the key, and relying on RocksDB's default
lexicographic byte array comparator, and hence negative long value stored in
RocksDB will cause the range search ordering to be messed up.
