Class AddToCell (2.32.0) 

AddToCell(family: str, qualifier: bytes | str, value: int, timestamp_micros: int)

Adds an int64 value to an aggregate cell. The column family must be an aggregate family and have an "int64" input type or this mutation will be rejected.

Note: The timestamp values are in microseconds but must match the granularity of the table (defaults to MILLIS). Therefore, the given value must be a multiple of 1000 (millisecond granularity). For example: 1571902339435000.

Methods

is_idempotent

is_idempotent() -> bool
