> Key: SPARK-18811
> URL: https://issues.apache.org/jira/browse/SPARK-18811
> Project: Spark
> Issue Type: Improvement
> Components: Structured Streaming
> Affects Versions: 2.0.2, 2.1.0
> Reporter: Burak Yavuz
>
> When you start a stream, if we are trying to resolve the source of the stream, for example if we need to resolve partition columns, this could take a long time. This long execution time should not block the main thread where `query.start()` was called on. It should happen in the stream execution thread possibly before starting any triggers.
