> Key: DRILL-8314
> URL: https://issues.apache.org/jira/browse/DRILL-8314
> Project: Apache Drill
> Issue Type: Improvement
> Components: Storage - Other
> Affects Versions: 1.20.2
> Reporter: James Turton
> Assignee: James Turton
> Priority: Minor
> Fix For: 2.0.0
>
>
> Enabled storage plugins may malfunction for different reasons, e.g. they have
> been misconfigured or their remote data source has gone offline. Depending on
> the plugin's implementation, this could cause it to fail to return optimizer
> rules or register schemas. In some cases this can have a wider impact, e.g.
> unconditioned queries against the info schema will fail if a single plugin is
> failing in registerSchemas.
> Rather than us swallowing such errors and silently returning a subset of
> results, this Jira proposes a new feature controlled by two SYSTEM options
> that, when enabled, means that a broken plugin will still cause a query
> failure but it will also disable the broken plugin after a configurable
> number of attempts and inform the user that is has done so. Knowing what has
> just happened, the user can choose to reissue the query knowing that the
> broken plugin is now disabled or they might choose to investigate the problem
> affecting the broken plugin instead.
