Module binary 

Modules

kernels 🔒

This module contains computation kernels that are specific to datafusion and not (yet) targeted to port upstream to arrow

Structs

BinaryExpr

Binary expression

Enums

ShortCircuitStrategy 🔒

Constants

PRE_SELECTION_THRESHOLD 🔒

Based on the results calculated from the left side of the short-circuit operation, if the proportion of true is less than 0.2 and the current operation is an and, the RecordBatch will be filtered in advance.

Functions

binary

Create a binary expression whose arguments are correctly coerced. This function errors if it is not possible to coerce the arguments to computational types supported by the operator.

boolean_op 🔒

Invoke a boolean kernel on a pair of arrays

check_short_circuit 🔒

Checks if a logical operator (AND/OR) can short-circuit evaluation based on the left-hand side (lhs) result.

concat_elements 🔒

pre_selection_scatter 🔒

Creates a new boolean array based on the evaluation of the right expression, but only for positions where the left_result is true.

similar_to

Create a similar to expression

to_result_type_array 🔒

Casts dictionary array to result type for binary numerical operators. Such operators between array and scalar produce a dictionary array other than primitive array of the same operators between array and array. This leads to inconsistent result types causing errors in the following query execution. For such operators between array and scalar, we cast the dictionary array to primitive array.
