----------------------------------------
Summary: Connect - Improve Memory Allocations During Struct
Validation
Key: KAFKA-8938
URL: https://issues.apache.org/jira/browse/KAFKA-8938
Project: Kafka
Issue Type: Improvement
Components: KafkaConnect
Reporter: Auston McReynolds
Summary: Struct value validation in Kafka Connect can be optimized to avoid
creating an Iterator when the expectedClasses list is of size 1. This is a
meaningful enhancement for high throughput connectors.
Stack Trace from the Couchbase Kafka Connector:
* java.util.Collections.singletonIterator(Object)
* java.util.Collections$SingletonList.iterator()
* org.apache.kafka.connect.data.ConnectSchema.validateValue(String, Schema,
Object)
* org.apache.kafka.connect.data.Struct.put(Field, Object)
* org.apache.kafka.connect.data.Struct.put(String, Object)
*
com.couchbase.connect.kafka.handler.source.DefaultSchemaSourceHandler.buildValue(SourceHandlerParams,
CouchbaseSourceRecord$Builder)
