This exposes additional options for AWS clients to the config files. These include: - Disabling request compression and min compression request size for cloudwatch - Disabling response checksum validation and accepting gzip compression for dynamodb - The usePathStyle setting was documented for S3 (but it was already exposed before) These settings are needed when talking to services implementing the AWS API like localstack or ScyllaDB as these services sometimes can't map all features exactly.
…onvert between normal and batch consumer callbacks; This allows you to use `application.RunBatchConsumer` similary to how you would use `application.RunConsumer` to run a batch consumer. It also adds `stream.ConsumerToBatchConsumer` and `stream.ConsumerToParallelBatchConsumer` to adapt single consumers to batch consumers. You should set stream.consumer.<name>.batch_size to take advantage of batching as it defaults to 1.

…unner; Right now, `stream.consumer.<consumer>.runner_count` must be equal to 1 when using the batch consumer as the batch consumer is not thread safe. This commit fixes this and thus allows processing and acknowledging more than one batch at once.
This commit allows the batch consumer to acknowledge aggregate messages. Until now, the consumer would struggle to find the correct message ids to delete the messages from something like SQS, making it impossible to actually acknowledge an aggregate message in a batch. We now correctly preserve the original message as well as added some delayed context cancels in case of needing to write a message to a retry queue (otherwise, the normal consumer would just lose the message if the queue doesn't have any native retry functionality).
