public final class TimestampSplit extends GeneratedMessageV3 implements TimestampSplitOrBuilder
Assigns input data to training, validation, and test sets based on a
provided timestamps. The youngest data pieces are assigned to training set,
next to validation set, and the oldest to the test set.
Supported only for tabular Datasets.

Required. The key is a name of one of the Dataset's data columns.
The values of the key (the values in the column) must be in RFC 3339
date-time format, where time-offset = "Z"
(e.g. 1985-04-12T23:20:50.52Z). If for a piece of data the key is not
present or has an invalid value, that piece is ignored by the pipeline.
string key = 4 [(.google.api.field_behavior) = REQUIRED];
