KB-1455 Kafka Logs using high amounts of disk space

Symptoms

The Kafka transaction logs in the <APPIAN_HOME>/services/data/kafka-logs directory are using large amounts of disk space. 

Cause

The transaction logs are responsible for storing transactions that have yet to be persisted to the KDBs on disk through checkpointing. These logs can grow large and use higher amounts of disk space if the system has not checkpointed for a significant amount of time.

Action

Initiate a checkpoint and verify that the disk usage in that directory has decreased. Ensure that configurations are not in place that delay or leave long periods between checkpointing. If the disk usage does not come down after checkpointing, contact Appian Technical Support.

Refer to the document on Configuring Application Checkpointing for more information. 

Affected Versions

This article applies to Appian 17.3 and later.
