Topic view

Overview​

Topic view is Signals' cluster-wide drill-down into topic-level risk. At the moment it provides insights into what we deem an operational risk for your cluster, potential misconfigurations and issues reducing your topic efficiency.

Operational risk monitoring​

An opinionated grouping around what poses topic-level operational risk. This section covers the following checks:

  • Offline leader: Partitions whose leader is on an offline broker.
  • Offline replicas: Partitions with a replica on an offline broker.
  • Under-replicated partitions: In-sync replica count below the topic's min.insync.replicas.
  • Below minimum replication factor: Replication factor below Kpow's configured minimum of 3.
  • Partition data skew: Partition sizes deviate from an even distribution.

Data Governance​

Data Governance section, at this stage, covers potential topic misconfigurations. I particular it highlights topics that have configurations where min.insync.replicas is below 2 or unclean.leader.election.enable is set to true.

Efficiency​

Efficiency section lists opportunities to cut cost and improve topic use. Atm, it includes the following checks:

  • Tiny partitions: Partition size below 1 MB.
  • Single partition, large topic: Single-partition topic exceeding 1 MB.
  • Inactive partitions: No writes in the last 7 days.
  • Empty partitions: No messages in a partition.
