SimpleTracker

public SimpleTracker(String consumerName,
 int maxSize,
 Consumer<MessageBatch> handler)

Method Details

ignoreSegment

public boolean ignoreSegment()

Specified by:

ignoreSegment in interface Tracker

Returns:

true if this tracker ignores segment-based filtering (i.e. processes all segments).

clientControlledIndex

public boolean clientControlledIndex()

Specified by:

clientControlledIndex in interface Tracker

Returns:

true if this tracker uses client-controlled index tracking (instead of store-side indexing).

getTrackerId

public String getTrackerId()

Specified by:

getTrackerId in interface Tracker

Returns:

the unique ID of this tracker instance.

getClientId

public String getClientId()

Specified by:

getClientId in interface Tracker

Returns:

the unique ID of the client, typically one per client application instance.

getPurgeDelay

public Long getPurgeDelay()

Specified by:

getPurgeDelay in interface Tracker

Returns:

the optional duration (in milliseconds) after which this tracker may be purged if it is actively processing messages (i.e., not idle or waiting).

This mechanism ensures that stale trackers are eventually cleaned up, particularly in scenarios where graceful disconnection is not guaranteed. This is especially relevant for external trackers — such as non-Java applications or clients not using Flux’s built-in client — which may not send an explicit disconnect.

In normal Flux client usage, purging should rarely occur, as disconnection is managed by the client.

send

public void send(MessageBatch batch)

Description copied from interface: Tracker

Sends a batch of messages to this tracker.

Specified by:

send in interface Tracker

Parameters:

batch - the batch to deliver

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object
