Christine Poerschke commented on SOLR-10610:
--------------------------------------------
ticket cross-reference: in SOLR-1687 [~janhoy] mentioned a generic
{{RequestSanitizerComponent}} he wrote. it sounds like there's some
similarities between the request sanitizer and canary components.
> Add CanaryComponent, a search component to analyse requests

> This patch outlines a new component that analyses a request and reports
> whether it is too complex to continue processing.
> Running this component should be conditional and happen before other
> components start processing. The component will set a status flag so that
> other components can know the result of the Canary check, and also adds some
> information to the response sent back to the client.
> In the future this could be used to process a query only on selected shards
> (canaries) and based on the outcome decide whether to continue on all shards.
> Please note this is only an outline so far.
