Dong Lin commented on KAFKA-5451: --------------------------------- Moving this to 2.2.0 since PR is not ready yet. > 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 > Priority: Major > Labels: performance > Fix For: 2.2.0 > > Original Estimate: 24h > Remaining Estimate: 24h > > 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
