Configure Intelligent Replication in Confluent Private Cloud

This topic describes the configuration options available for tuning Intelligent Replication performance in Confluent Private Cloud.

Configuration properties

The following configurations are available for tuning Intelligent Replication:

Property

Type

Default Value

Description

confluent.intelligent.replication.push.max.threads

INT

4

Determines the maximum number of threads to be used for push replication.

confluent.intelligent.replication.push.threads.per.remote.broker

INT

1

Determines the number of threads replicating to a single peer broker. Can be between 1 and the setting for confluent.intelligent.replication.push.max.threads.

confluent.intelligent.replication.push.max.memory.buffer.bytes

LONG

209715200 (200 MB)

The maximum amount of memory used by push replication for buffering. Currently used solely by the records buffer for intelligent replication.

Review configuration guidelines

Thread Configuration

  • Max Threads: The confluent.intelligent.replication.push.max.threads setting controls the total thread pool size for push replication across all remote brokers.

  • Threads Per Broker: The confluent.intelligent.replication.push.threads.per.remote.broker setting determines how many threads are dedicated to each remote broker.

  • Relationship: The threads per broker setting cannot exceed the max threads setting.

Memory Configuration

  • Buffer Size: The confluent.intelligent.replication.push.max.memory.buffer.bytes setting controls memory allocation for push replication buffering.

  • Monitoring: Use the PushManagerMemoryBytesUsed metric to monitor actual memory usage against this limit.
