------------------------------------
Summary: Kafka Connect should scan classpath asynchronously
Key: KAFKA-5451
URL: https://issues.apache.org/jira/browse/KAFKA-5451
Project: Kafka
Issue Type: Improvement
Components: KafkaConnect
Affects Versions: 0.11.0.0
Reporter: Randall Hauch
Assignee: Randall Hauch
Fix For: 0.11.1.0
When Kafka Connect workers start up, they scan the classpath and module paths
for connectors, transformations, and converters. This takes anywhere from
15-30sec or longer depending upon how many JARs are included. Currently, this
scanning is done synchronously during startup of the Kafka Connect workers,
even though the workers may not need the result of the scan.
The scanning logic should be asynchronous and should only block any components
that require the result of the scan. This will improve startup time of the
workers.
