Interview room
DR for multi-region pipelines: replication, failover, RTO/RPO. Numbers before logos.
Basics
RPO/RTO definitions; active-passive vs active-active; replicate data+offsets+configs; drills required.
Prompt
Numeric targets, cross-region mirror, failover, fencing, cost, drills.
Good
Numbers; diagram; runbook; failback; game days.
Clarify/scope
Active mode; RPO minutes vs hours; residency.
Scoring lens: Disaster Recovery for Multi-Region Pipeline
Interviewers reward incident-first teaching, a clear control loop, and named owners. Tool logos without that loop score poorly.
Weak vs strong answers on Disaster Recovery for Multi-Region Pipeline
Weak: list products. Strong: tell the failure story, define the mechanism, draw the path, state rollout and monitors.
Scope control
Say what is out of scope for v1. Come back only if follow-ups demand it. This is a seniority signal for Disaster Recovery for Multi-Region Pipeline.
Clarifying then committing
Ask a few high-use questions about SLAs, owners, and scale, then sketch. Endless questions without a diagram look evasive.
Control-plane checklist
Images, secrets, IAM, DNS, job configs, schema registry connectivity in region B. Data bytes without control plane readiness fail drills.
Idempotent sinks and DR
Approximate offset restart is survivable if sinks upsert idempotently. Connect DR talk to everyday effectively-once design.
Failback is a second incident
Plan catch-up of A from B, drain, and cutover. Untested failback creates the sequel outage.
Interview framing detail 1
For lb-sd-35, spend the first minutes making the problem concrete: who gets hurt when this fails, what SLA is implied, and what is explicitly out of scope. Then teach the prerequisite concept before proposing boxes. A candidate who names vendors first usually loses the plot. Write two clarifying questions on the board and answer them with assumptions if the interviewer shrugs. Keep the first diagram small enough to redraw when a follow-up changes a constraint.
