Till Rohrmann created FLINK-6768: ------------------------------------ Summary: Quadratic/Inefficient field lookup in PojoSerializer#ensureCompatibility Key: FLINK-6768 URL: https://issues.apache.org/jira/browse/FLINK-6768 Project: Flink Issue Type: Improvement Components: State Backends, Checkpointing, Type Serialization System Affects Versions: 1.3.0, 1.4.0 Reporter: Till Rohrmann Priority: Minor
In the {{PojoSerializer#ensureCompatibility}} method we call for each field in the {{PojoSerializerConfigSnapshot}} the {{findField}} method which executes a linear scan of the array of fields of the {{PojoSerializer}}. This effectively has a quadratic runtime and could be done more efficiently. For example, we could construct a {{HashMap}} containing the fields as keys and the index as values. That way we would have a have a better lookup performance. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
