Validate validates the logical plan.

ValidateAggregation validates the logical plan's aggregation step.

ValidateComparingTypes validates if the types being compared by a binary expression are compatible.

ValidateFilter validates the logical plan's filter step.

ValidateFilterAndBinaryExpr validates the filter's binary expression where Op = AND.

ValidateFilterBinaryExpr validates the filter's binary expression.

ValidateFilterExpr validates filter's expression.

ValidateInput validates that the current logical plans input is valid.

ValidateSingleFieldSet checks that only a single field is set on the plan.

ReadModeDataSourcesOnly reads from data sources only.

ReadModeDefault is the default read mode.

ReadModeInMemoryOnly reads from in-memory storage only.

AggFuncPushDown optimizer tries to push down an aggregation function operator to the table provider.

DistinctPushDown optimizer tries to push down the distinct operator to the table provider.

ExprValidationError is the error for an invalid expression that was found during validation.

FilterPushDown optimizer tries to push down the filters of a query down to the actual physical table scan.

IterOptions are a set of options for the TableReader Iterators.

LogicalPlan is a logical representation of a query.

PhysicalProjectionPushDown finds the first projecting logical plan and collects all columns it needs, it is concatenated with all other columns used until it, for example a filter layer.

PlanValidationError is the error representing a logical plan that is not valid.

Callback is a function that is called throughout a chain of operators modifying the underlying data.
