Class KeyedTimerData.KeyedTimerDataCoder<K>

java.lang.Object

org.apache.beam.sdk.coders.Coder<T>

org.apache.beam.sdk.coders.StructuredCoder<KeyedTimerData<K>>

org.apache.beam.runners.samza.runtime.KeyedTimerData.KeyedTimerDataCoder<K>

All Implemented Interfaces:

java.io.Serializable

Enclosing class:

KeyedTimerData<K>

public static class KeyedTimerData.KeyedTimerDataCoder<K>
extends org.apache.beam.sdk.coders.StructuredCoder<KeyedTimerData<K>>

Coder for KeyedTimerData. Note we don't use the TimerInternals.TimerDataCoderV2 here directly since we want to en/decode timestamp first so the timers will be sorted in the state.
