Jacob Park created FLINK-9083: --------------------------------- Summary: Add async backpressure support to Cassandra Connector Key: FLINK-9083 URL: https://issues.apache.org/jira/browse/FLINK-9083 Project: Flink Issue Type: Improvement Components: Cassandra Connector Reporter: Jacob Park
As the CassandraSinkBase derivatives utilize async writes, they do not block the task to introduce any backpressure. I am currently using a semaphore to provide backpressure support by blocking at a maximum concurrent requests limit like how DataStax's Spark Cassandra Connector functions: [https://github.com/datastax/spark-cassandra-connector/blob/v2.0.7/spark-cassandra-connector/src/main/scala/com/datastax/spark/connector/writer/AsyncExecutor.scala#L18] This improvement has greatly improved the fault-tolerance of our Cassandra Sink Connector implementation on Apache Flink in production. I would like to contribute this feature back upstream. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
