Summary: Iterating over cache with get(key) is inefficient Key: KAFKA-8094 URL: https://issues.apache.org/jira/browse/KAFKA-8094 Project: Kafka Issue Type: Improvement Reporter: Sophie Blee-Goldman Currently, range queries in the caching layer are implemented by creating an iterator over the subset of keys in the range, and calling get() on the underlying TreeMap for each key. While this protects against ConcurrentModificationException, we can improve performance by replacing the TreeMap with a concurrent data structure such as ConcurrentSkipListMap and then just iterating over a subMap. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
