Guide safe cancellation of Redis Cloud subscriptions across direct Redis billing, AWS Marketplace, and GCP Marketplace. Use when the user asks to cancel or delete a Redis Cloud subscription, cannot find the Cancel Subscription button, is blocked by unpaid invoices, needs to cancel marketplace billing, or asks why billing continued after cancellation.
Safely guide Redis Cloud database deletion and related billing cleanup. Use when the user asks to delete a Redis Cloud database, remove a database from the console, automate deletion through API or Terraform, delete a subscription after deleting databases, stop billing, troubleshoot missing Delete Database buttons, or handle AWS/GCP Marketplace-linked subscriptions.
Use when Redis Enterprise for Kubernetes applications fail to connect after Kubernetes Secret, REDB authentication, passwordless access, ACL/user, TLS certificate, service, DNS, or network policy changes, especially WRONGPASS, NOAUTH, NOPERM, auth failed, timeout, disconnect, stale Secret, application pods not restarted, or REDB/operator reconciliation issues.
Safely place Redis Enterprise Software nodes into maintenance mode for OS patching, reboot, hardware work, or node service maintenance. Use when the user asks how to patch Redis Software nodes, run `maintenance_mode on/off`, demote a master node, migrate shards off a node, preserve quorum, avoid multiple nodes in maintenance, restore snapshots, or verify node maintenance completion.
Recover a Redis Enterprise Software database after accidental `FLUSHDB` by preserving and trimming AOF files. Use when the user asks about AOF-based recovery, locating per-shard appendonly files, removing destructive commands from AOF, disabling/enabling watchdogs, using `preload-file`, restarting shards with `redis_ctl force-start`, or deciding when to restore from backup instead. Do not use for Active-Active CRDB recovery when healthy replicas exist.
Prevent and troubleshoot HTTP 429 rate-limit errors in Redis-related automation, CI/CD pipelines, Terraform workflows, Redis Cloud API scripts, and scripted Redis Insight/client activity. Use when the user mentions 429 responses, Retry-After, bursty pipelines, polling loops, Terraform parallelism, CI job concurrency, API throttling, or retries that make rate limits worse.
Triage Azure Redis Enterprise connection storms and health-check load differences between ACRE and AMR, including VM-level connection caps, dmcproxy CPU saturation, proxy restart loops, SLO degradation without shard failure, load balancer per-source limits, health-check concurrency, idle timeout tuning, OS file descriptor and backlog checks, `ss -antp` source analysis, and deciding when AMR-enforced connection ceilings or Support escalation are needed.
Safely delete large numbers of Redis keys without production latency spikes. Use when the user asks to delete keys by pattern, avoid `KEYS` or blocking `DEL`, use `SCAN` plus `UNLINK`, handle CROSSSLOT errors in clustered or Active-Active databases, use Redis Insight Bulk Actions, or reclaim memory after massive deletion.
