Method Details

supportedActions

default List<RegionedPushdownAction> supportedActions()

Get the list of pushdown actions supported by this matcher. Defaults to an empty list.

makeEstimateContext

default RegionedPushdownAction.EstimateContext makeEstimateContext(WhereFilter filter,
 PushdownFilterContext context)

Create a context for estimating the cost for the filter and filter context. This context can be used to provide additional information to the estimatePushdownAction(io.deephaven.engine.table.impl.sources.regioned.RegionedPushdownAction, io.deephaven.engine.table.impl.select.WhereFilter, io.deephaven.engine.rowset.RowSet, boolean, io.deephaven.engine.table.impl.PushdownFilterContext, io.deephaven.engine.table.impl.sources.regioned.RegionedPushdownAction.EstimateContext) function

estimatePushdownAction

default long estimatePushdownAction(RegionedPushdownAction action,
 WhereFilter filter,
 RowSet selection,
 boolean usePrev,
 PushdownFilterContext filterContext,
 RegionedPushdownAction.EstimateContext estimateContext)

Estimate the cost of the given pushdown action. Returns Long.MAX_VALUE if the action is not supported by this matcher.

makeActionContext

default RegionedPushdownAction.ActionContext makeActionContext(WhereFilter filter,
 PushdownFilterContext context)

Create a context for processing the given filter and filter context. This context can be used to provide additional information to the performPushdownAction(io.deephaven.engine.table.impl.sources.regioned.RegionedPushdownAction, io.deephaven.engine.table.impl.select.WhereFilter, io.deephaven.engine.rowset.RowSet, io.deephaven.engine.table.impl.PushdownResult, boolean, io.deephaven.engine.table.impl.PushdownFilterContext, io.deephaven.engine.table.impl.sources.regioned.RegionedPushdownAction.ActionContext) function

performPushdownAction

default PushdownResult performPushdownAction(RegionedPushdownAction action,
 WhereFilter filter,
 RowSet selection,
 PushdownResult input,
 boolean usePrev,
 PushdownFilterContext filterContext,
 RegionedPushdownAction.ActionContext actionContext)

Perform the pushdown action for the given filter and filter context.
