Can 2 WHEN case statements distribute events to same stream via Router ?

I am trying to modify an existing Striim App which routes events based on the table name to different Target Writers. I would like to know if two different WHEN statements can be routed to the same stream. Based on the Striim Router documentation here . Can the sample code be modified to route the events of two case statements to `stream_one` as shown below. CREATE ROUTER myRouter INPUT FROM mySourceStream AS src CASE WHEN TO_INT(src.data[1]) < 150 THEN ROUTE TO stream_one, WHEN TO_INT(src.data[1]) >= 150 THEN ROUTE TO stream_two, WHEN meta(src,"TableName").toString() like 'QATEST.TABLE_%' THEN ROUTE TO stream_one,ELSE ROUTE TO stream_else;Exploring other possible ways to resolve the above issue - Is it possible to write the above as a Boolean logic? CREATE OR REPLACE ROUTER myRouter INPUT FROM mySourceStream AS srcCASE WHEN meta(src,"TableName").toString() like 'QATEST.USERS' THEN ROUTE TO stream_one OR WHEN meta(src,"TableName").toString() like 'QATEST.ACCOUNTS' THEN ROUTE

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

Parallel Threads causes out of order events during CDC [SOLVED]

we’ve observed a number of lost updates when running CDC. The state of initial load seems fine, but later on we came across NO_OP_UPDATES. I’ve ignored the exception for the CDC, but that resulted in some of the updates being lost and records left in stale state.It seems that it might be connected with updates being in the same batch as the initial insert. How are events ordered within a single batch? Have you observed such scenarios? Source is SQL Server and target is Postgres in case thats relevant.
