| Configuration | Description | Values |
|---|---|---|
group.coordinator.rebalance.protocols | The list of enabled rebalance protocols. (Existing configuration) |
This will be added to the default value of this configuration property once this feature is complete. |
group.share.delivery.count.limit | The maximum number of delivery attempts for a record delivered to a share group. | Default 5, minimum 2, maximum 10 |
group.share.record.lock.duration.ms | Share-group record acquisition lock duration in milliseconds. | Default 30000 (30 seconds), minimum 1000 (1 second), maximum 60000 (60 seconds) |
group.share.min.record.lock.duration.ms | Share-group record acquisition lock minimum duration in milliseconds. | Default 15000 (15 seconds), minimum 1000 (1 second), maximum 30000 (30 seconds) |
group.share.max.record.lock.duration.ms | Share-group record acquisition lock maximum duration in milliseconds. | Default 60000 (60 seconds), minimum 30000 (30 seconds), maximum 3600000 (1 hour) |
group.share.partition.max.record.locks | Share-group record lock limit per share-partition. | Default 200, minimum 100, maximum 10000 |
group.share.session.timeout.ms | The timeout to detect client failures when using the group protocol. | Default 45000 (45 seconds) |
group.share.min.session.timeout.ms | The minimum session timeout. | Default 45000 (45 seconds) |
group.share.max.session.timeout.ms | The maximum session timeout. | Default 60000 (60 seconds) |
group.share.heartbeat.interval.ms | The heartbeat interval given to the members. | Default 5000 (5 seconds) |
group.share.min.heartbeat.interval.ms | The minimum heartbeat interval. | Default 5000 (5 seconds) |
group.share.max.heartbeat.interval.ms | The maximum heartbeat interval. | Default 15000 (15 seconds) |
group.share.max.groups | The maximum number of share groups. | Default 10, minimum 1, maximum 100 |
group.share.max.size | The maximum number of consumers that a single share group can accommodate. | Default 200, minimum 10, maximum 1000 |
group.share.assignors | The server-side assignors as a list of full class names. The list must contain only a single entry which is used by all groups. In the future, it is envisaged that a group configuration will be provided to allow each group to choose one of the list of assignors. | A list of class names, currently limited to a single entry. Default "org.apache.kafka.coordinator.group.share.SimpleAssignor" |
share.coordinator.state.topic.num.partitions | The number of partitions for the share-group state topic (should not change after deployment). | Default 50 |
share.coordinator.state.topic.replication.factor | The replication factor for the share-group state topic (set higher to ensure availability). Internal topic creation will fail until the cluster size meets this replication factor requirement. | Default 3 (specified as 1 in the example configuration files delivered in the AK distribution for single-broker use) |
share.coordinator.state.topic.segment.bytes | The log segment size for the share-group state topic. | Default 104857600 |
share.coordinator.state.topic.min.isr | Overridden min.insync.replicas for the share-group state topic. | Default 2 (specified as 1 in the example configuration files delivered in the AK distribution for single-broker use) |
share.coordinator.state.topic.compression.codec | Compression codec for the share-group state topic. | Default 0 (NONE) |
share.coordinator.append.linger.ms | The duration in milliseconds that the share coordinator will wait for writes to accumulate before flushing them to disk. | Default 10, minimum 0 |
share.coordinator.load.buffer.size | Batch size for reading from the share-group state topic when loading state information into the cache (soft-limit, overridden if records are too large). | Default 5 * 1024 * 1024 (5242880), minimum 1 |
share.coordinator.snapshot.update.records.per.snapshot | The number of update records the share coordinator writes between snapshot records. | Default 500, minimum 0 |
share.coordinator.threads | The number of threads used by the share coordinator. | Default 1, minimum 1 |
share.coordinator.write.timeout.ms | The duration in milliseconds that the share coordinator will wait for all replicas of the share-group state topic to receive a write. | Default 5000, minimum 1 |
