Class RowBundle<T>

org.apache.beam.sdk.jmh.schemas.RowBundle<T>

Direct Known Subclasses:

public class RowBundle<T>
extends java.lang.Object

Bundle of rows according to the configured Factory as input for benchmarks.

When reading, rows are created during setup() to exclude initialization costs from the measurement. To prevent unintended cache hits in RowWithGetters, a new bundle of rows must be generated before every invocation.

Setup per Level.Invocation has considerable drawbacks. Though, given that processing bundles of rows (n=bundleSize) takes well above 1 ms, each individual invocation can be adequately timestamped without risking generating wrong results.
