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.

adjusting timezone

I’d like to convert a timestamp from location specific one (in areas that have summer time change) to UTC. What would be the best way to do it within Striim? I assume it’s doable using Joda API and I can see in the reference that “Striim supports all date functions natively associated with Joda-Time.” but I didn’t find an example how to call those Joda Time functions

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.

CDC Postgres UUID to SQL Servers uniqueidentifier

Hi all, I’m trying to set up a CDC from Postgres(GCP Cloud SQL if it makes any difference) of a table with a UUID column to a SQL Server table with uniqueidentifier column. The wizard says it’s not possible. I’ve tried mapping the tables manually, but all the rows end up being discarded. Is there any way to make it work? Similar migration in the opposite direction works.

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.
