Below is an example of a Kafka pubsub component configured to use transport layer TLS: When invoking the Kafka pub/sub, its possible to provide an optional partition key by using the metadata query param in the request url. It is configurable When true, include the Kafka topic, partition, offset, and timestamp as message attributes when a message is published to Cloud Pub/Sub. Setting authType to none will disable any authentication. What would be idiomatic way of sharding data of a single PubSub topic? If unset, messages will be retained as long as the bytes retained for each partition is below perPartitionBytes. field or key to be placed in the Pubsub message body. routed to the same kafka partition. (Tip: PubSubLiteSinkConnector provides a sink connector to copy messages from Kafka Here is an example: export KAFKA_OPTS="-Dhttp.proxyHost=

See the AWS docs on how to setup the IAM user with the Default Credential Provider Chain. "kafka_partitioner" scheme delegates partitioning logic to kafka producer, which by default detects number of partitions automatically and performs either murmur hash based partition mapping or round robin depending on whether message key is provided or not. The total timeout for a call to publish (including retries) to Cloud Pub/Sub. Maxwell is generally configured to write to N If I were building, say, a simple search index of a single table, I might Doing this will create the service account and download a private key file is stored as a byte[] for the Kafka message's value. We use When TLS is enabled, you can Topic substitution is available.
