Struct mz_adapter::coord::sequencer::inner::create_continual_task::NoIndexCatalog

source · 
struct NoIndexCatalog {
    delegate: Arc<dyn OptimizerCatalog>,
}
Expand description

An OptimizerCatalog impl that ignores any indexes that exist.

TODO(ct3): At the moment, the dataflow rendering for CTs only knows how to turn persist_sources into CT inputs. If the optimizer decides to use an existing index in the cluster, it won’t work. It seems tricky/invasive to fix the render bug, so for now pretend indexes don’t exist for CTs. Remove this once we fix the bug.
