Example 9 with MetricsSnapshotSerdeV2

use of org.apache.samza.serializers.MetricsSnapshotSerdeV2 in project samza by apache.

the class TestMetricsSnapshotSerdeV2 method testDeserializeRaw.

/**
 * Helps for verifying compatibility when schemas evolve.
 *
 * Maps have non-deterministic ordering when serialized, so it is difficult to check exact serialized results. It
 * isn't really necessary to check the serialized results anyways. We just need to make sure serialized data can be
 * read by old and new systems.
