Constructor Details

ConstraintApplicationResult

public ConstraintApplicationResult(T handle,
 TupleDomain<ColumnHandle> remainingFilter,
 boolean precalculateStatistics)

Parameters:

precalculateStatistics - Indicates whether engine should consider calculating statistics based on the plan before pushdown, as the connector may be unable to provide good table statistics for handle.

ConstraintApplicationResult

public ConstraintApplicationResult(T handle,
 TupleDomain<ColumnHandle> remainingFilter,
 ConnectorExpression remainingExpression,
 boolean precalculateStatistics)

Parameters:

remainingExpression - the remaining expression, which will be AND-ed with remainingFilter,

precalculateStatistics - Indicates whether engine should consider calculating statistics based on the plan before pushdown, as the connector may be unable to provide good table statistics for handle.
