Hanyu Zheng updated FLINK-36898:
--------------------------------
Description:
Currently, Flink does not support nanosecond precision for the CEIL and FLOOR
functions. This limitation exists because Flink does not have a data type with
precision greater than nanoseconds. To introduce support for nanoseconds in
these functions, we would first need to evaluate whether this level of
precision is required. If the requirement is confirmed, it may necessitate the
creation of a new data type with higher precision.
This ticket aims to:
# Investigate the need for nanosecond precision in CEIL and FLOOR functions.
# Analyze the technical feasibility of extending Flink's type system to
support nanoseconds in ceil and floor functions.
# Identify potential changes required across Flink's core components,
including data types, functions, and runtime execution.
This research will guide whether a subsequent implementation task is needed to
support the datatype which precision is higher than nanosecond.
