MySQL Reader + KafkaWriter: How to specify individual topics for the individual MySQL tables?

Hey! I have the following setup:MySQL → Striim → KafkaThis all works as expected, but if I have multiple MySQL tables, all changes are streamed into 1 single Kafka topic.Is there a way to configure the KafkaWriter to stream the messages to dedicated topics for each table?For exmaple:Events from table `users` should go to a topic `users` Events from table `items` should go to a topic `itmes`As far as I can see in the docs, you can only specify one topic per KafkaWriter.

Suitable Avro type not found for field error when using MySQL -> Striim -> Kafka

I’ve got the following setup:MySQL → Striim → Kafka + CSR and avro encoding The table that I’m replicating is pretty simple: items | CREATE TABLE `items` (  `id` bigint unsigned NOT NULL AUTO_INCREMENT,  `name` varchar(100) DEFAULT NULL,  `category` varchar(100) DEFAULT NULL,  `price` decimal(7,2) DEFAULT NULL,  `inventory` int DEFAULT NULL,  `inventory_updated_at` timestamp NULL DEFAULT CURRENT_TIMESTAMP,  `created_at` timestamp NULL DEFAULT CURRENT_TIMESTAMP,  `updated_at` datetime DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,  PRIMARY KEY (`id`),  UNIQUE KEY `id` (`id`)) ENGINE=InnoDB AUTO_INCREMENT=2001 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci However the bigint seems to be causing the following error when Striim starts ingesting messages:Message: KafkaWriter is unable to produce events to shop. Component Name: Kafka_2_1_0_mysql_kafka_csr_Target. Component Type: TARGET. Cause: KafkaWriter is unable to produce events to shop. Cause: Suitable Avro type not found fo

MySQL to Kafka+CSR

Trying to set up:Source: MySQL replication hosted in RDS, which works on its ownTarget: Kafka (works on its own) + CSR (untested) hosted on Confluent Cloud--using the AvroFormatter.The CSR is untested bc it doesn't seem like CSR is supported w/ the builtin load generators--though maybe I'm wrong.When I deploy it, I get:Error Deploy failed! java.util.concurrent.ExecutionException: java.lang.reflect.InvocationTargetExceptionI’ve tested the connection to the CSR and it works, so I don’t believe it’s a credential issue.

Forwarding Agent encryption in transit

While it’s great that you offer a Forwarding Agent for sources/destinations that have no direct public IP, I’m having a hard time finding any information as to whether or what sort of encryption in transit is used for the data conveyed by the Agent. And before I go digging into testing what it appears to do, I thought I’d ask here:  Does Striim Forwarding Agent use any encryption for any of its communication?Context here is that it was suggested to me that Striim might be useful in migrating from an antiquated MySQL ring replication cluster to a modern MySQL master-master cluster. Neither source nor destination cluster has, nor will have, a public IP address, and will not have any direct access available to to the greater internet.

How do we flatten JSON in Striim?

I have a JSON Field in my PostgreSQL database with this format I want to take all the fields in this flat JSON structure and turn each of them into fields in a typed stream. How would I go about doing that? I tried using the ‘makeJSON’ function on the JSON string column but I’m unable to run JSONNode function on it.  Running the above query results in a ‘CRASH, cannot map’ exception.
