Class StatsAggregator

大牛时代配资A stateful resource that aggregates statistics from one or more iterators.


  • Class

To record statistics, use one of the custom transformation functions defined in this module when defining your All statistics will be aggregated by the StatsAggregator that is associated with a particular iterator (see below). For example, to record the latency of producing each element by iterating over a dataset:

dataset = ...
dataset = dataset.apply("total_bytes"))

To associate a StatsAggregator with a object, use the following pattern:

aggregator =
dataset = ...

# Apply `StatsOptions` to associate `dataset` with `aggregator`.
options =
options.experimental_stats.aggregator = aggregator
dataset = dataset.with_options(options)

Note: This interface is experimental and expected to change. In particular, we expect to add other implementations of StatsAggregator that provide different ways of exporting statistics, and add more types of statistics.
