> Project: Ignite
> Issue Type: Bug
> Reporter: Aleksey Plekhanov
> Assignee: Aleksey Plekhanov

> Labels: calcite2-required, calcite3-required
> Time Spent: 10m
> Remaining Estimate: 0h

> The static instance of {{RelOptCluster}} accumulates data in the cache
> (\{{BaseQueryContext.CLUSTER.mq.map}}) and never clear it. We should attach
> the new cluster query fragments during each mapping and detach it before
> storing the query plan in the query plan cache.
