PowerExchange CDC Publisher can print runtime statistics to the message log at shutdown if you set the new

Connector.logConnectorStatsOnExit

property to true in the cdcPublisherKafka.cfg configuration file. The statistics are printed in message CDCPUB_15034 and are the same as the statistics produced by the PWXCDCINFO STATS=TOPIC command.

PowerExchange CDC Publisher now supports the use of period (.) and dash (-) characters in Kafka topic names if you set the new

Connector.kafkaTopicAllowSpecialCharacters

parameter to true.

To support exactly-once delivery of messages to the target, PowerExchange CDC Publisher now detects when the Kafka enable.idempotence property is set to true in the producer.properties file. When idempotence is enabled, the retries parameter in the Kafka Streams client configuration must be set to a value greater than 0. Previously, CDC Publisher reset the retries parameter to 0 when using

guaranteed delivery

. Now, CDC Publisher honors a retries parameter value greater than 0 when idempotence is enabled and guaranteed delivery is in use.

PowerExchange CDC Publisher can generate a composite message key for each source table based on rules that you define. The message key is included in the messages that CDC Publisher sends to the target messaging system. The target messaging system can use the message key to write messages with a specific key value to the same partition in the target topics.
