DEFAULT_ASYNC_BUFFER_SIZE

public static final int DEFAULT_ASYNC_BUFFER_SIZE

The max number of messages to hold in memory in case of transient socket errors. The maximum message size is 256 KB meaning the maximum size of this buffer would be 25.6 MB

Constant Field Values

MAX_ATTEMPTS_PER_MESSAGE

public static final int MAX_ATTEMPTS_PER_MESSAGE

How many times to retry an individual message. We eventually give up vs. retrying indefinitely in case there is something inherent to the message that is causing the failures. Giving up results in data loss, but also helps us reduce the risk of a poison pill blocking all process telemetry.

MIN_BACKOFF_MILLIS

public static final int MIN_BACKOFF_MILLIS

Starting backoff millis when a transient socket failure is encountered.
