pyarrow.compute.count(array, *, memory_pool=None, options=None, skip_nulls=True, min_count=1)

Count the number of null / non-null values.

By default, only non-null values are counted. This can be changed through ScalarAggregateOptions.

  • array (Array-like) – Argument to compute function

  • memory_pool (pyarrow.MemoryPool, optional) – If not passed, will allocate memory from the default memory pool.

  • options (pyarrow.compute.ScalarAggregateOptions, optional) – Parameters altering compute function semantics

  • **kwargs (optional) – Parameters for ScalarAggregateOptions constructor. Either options or **kwargs can be passed, but not both at the same time.
