Body: Storm 2.6.0.2 is out now. This patch focuses on stability and reliability with several key fixes and minor improvements:
(the master node) and resource leaks caused by certain file system operations. Apache Archives Security and Vulnerability Management Security is a primary driver for the 2.6.x minor releases. Library Updates : Critical libraries such as
Bolts handle all the data processing logic within the topology. They can perform functions such as: Filtering and transforming tuples. Aggregating metrics over time windows.
A stream is an unbounded sequence of tuples that is created and processed parallelly by spouts and bolts. A tuple is a named list of values, which can contain any data type as long as it can be serialized. 2. Key Enhancements in Version 2.6.0.2 storm 2.6.0.2

Align the number of executors with the number of CPU cores allocated to the worker.
Introduced three levels of idling (No Waiting, Park Nanos, and Thread Sleep) to conserve CPU during low-traffic periods.
Investigate if a specific bolt is blocking. Optimize heavy database I/O loops by shifting to asynchronous client drivers or batching mechanisms. Conclusion Library Updates : Critical libraries such as Bolts

While Storm’s native Kafka spout (org.apache.storm.kafka.spout.KafkaSpout) has “at-least-once” guarantees, the exact once (transactional) mode had a bug in offset management under replay scenarios. corrects the KafkaSpoutRetryExponentialBackoff logic, preventing duplicate offset commits.
