Cribl Architecture & Components 2

Question 1

In a Cribl Stream distributed deployment, which node type manages Worker node configuration and orchestrates the cluster?

Accepted Answer

Leader node

Answer

The Leader node holds the authoritative configuration and pushes it to Worker nodes, while Workers handle actual data processing.

Question 2

What is a Cribl Stream 'Worker Group'?

Accepted Answer

A logical grouping of Worker nodes that share the same configuration and routes

Answer

Worker Groups allow administrators to apply a consistent set of sources, routes, pipelines, and destinations to multiple Worker nodes simultaneously.

Question 3

If a Cribl Stream Leader node becomes temporarily unavailable in a distributed deployment, what happens to Worker nodes?

Accepted Answer

Worker nodes continue processing data using their last known cached configuration

Answer

Worker nodes cache their configuration locally and continue processing data independently, making the data plane resilient to control-plane outages.

Question 4

Which of the following best describes Cribl.Cloud?

Accepted Answer

A fully managed SaaS offering where Cribl operates the Leader node infrastructure

Answer

Cribl.Cloud provides a managed control plane so organizations can use Cribl Stream without managing Leader infrastructure themselves.

Question 5

What is the primary purpose of Persistent Queues in Cribl Stream?

Accepted Answer

To buffer events locally on a Worker when a destination becomes unavailable, preventing data loss

Answer

Persistent Queues provide a disk-based buffer that absorbs backpressure and prevents event loss when downstream destinations are slow or unavailable.
