Field Detail

batchLimitEvents

public final int batchLimitEvents

Maximum amount of events in batch. If it's reached, batch is sent immediately and stream is flushed.

batchTimeoutMillis

public final long batchTimeoutMillis

Timeout for collecting batchLimitEvents events. If not collected - send either not full batch or keep alive message.

streamTimeoutMillis

public final java.util.Optional<java.lang.Long> streamTimeoutMillis

Stream time to live

windowSizeMessages

public final int windowSizeMessages

commitTimeoutMillis

public final long commitTimeoutMillis
