QUESTION
When running dbt jobs in Meltano, dbt run
jobs may collide with each other if run out of a triggered context - for instance, when an on-demand job collides with a scheduled job or a CI-based job.
If dbt run
operates on the same tables at the same time, this generally causes a crash and sometimes a data quality issue if the same insert is performed twice on a single target table.
Any way to prevent run collisions, using either Meltano functionality or native dbt functionality?
...ANSWER
Answered 2021-Dec-16 at 18:22One way is to generate a lock in your target database. Here's an example for MSSQL.
I chose a on-run-start: hook. This hook attempts to grab a lock for dbt that lasts for the duration of the DB session.
dbt_project.yml

QUESTION
I'm playing a bit with Monk.io and Kafka - Meltano integration. So, I would like to create a Monk.io Kafka cluster and provision a new connection on Meltano. I'm using https://github.com/lensesio/fast-data-dev for Kafka env. What would be the best approach and have the most sense? I've planed to do it this way: Create runnables of Kafka and Meltano and create Monk actions for Meltano template. Those actions would have custom Meltano loader that would provide pipe to Kafka.
...ANSWER
Answered 2021-Feb-09 at 21:23I haven't tested the integration with Kafka but should be similar to Postgres in terms of execution in actions i.e to add a loader or extractor if those Kafka plugins exist for Meltano.
