Modifiable Broker Settings
Instaclustr Apache Kafka clusters are configured with optimal settings for our managed service. If required, the following Kafka broker configuration items can be changed by submitting a support request.
|auto.create.topics.enable||Enable auto creation of topic on the server||boolean||true|
|delete.topic.enable||Enables delete topic. Delete topic through the admin tool will have no effect if this config is turned off||boolean||true|
|default.replication.factor||default replication factors for automatically created topics||int||3|
|num.partitions||The default number of log partitions per topic||int||3|
|log.retention.bytes *||The maximum size of the log before deleting it||long||-1|
|log.retention.hours *||The number of hours to keep a log file before deleting it (in hours), tertiary to log.retention.ms property||int||168|
|log.retention.minutes *||The number of minutes to keep a log file before deleting it (in minutes), secondary to log.retention.ms property. If not set, the value in log.retention.hours is used||int||null|
|log.retention.ms *||The number of milliseconds to keep a log file before deleting it (in milliseconds), If not set, the value in log.retention.minutes is used||long||null|
|group.initial.rebalance.delay.ms||The amount of time the group coordinator will wait for more consumers to join a new group before performing the first rebalance. A longer delay means potentially fewer rebalances, but increases the time until processing begins.||int||3000|
|num.network.threads||The number of threads that the server uses for receiving requests from the network and sending responses to the network||int||3|
|compression.type||Specify the final compression type for a given topic. This configuration accepts the standard compression codecs (‘gzip’, ‘snappy’, ‘lz4’). It additionally accepts ‘uncompressed’ which is equivalent to no compression; and ‘producer’ which means retain the original compression codec set by the producer.||string||producer|
* These log settings are only applicable for topics that are created via auto topic creation. These settings can be specified on a per topic basis when the topic is created explicitly.
