Migration Considerations

Migration Step 1

Realtime Collaborative Editor

Short-polling API with version-based conflict detection → WebSocket + Redis pub/sub live propagation

Streaming Media Platform

Synchronous transcoding in the upload request handler (blocking API response) → Async transcoding via Kafka topic with competing consumer workers

Both scenarios define a migration step at this stage. Realtime Collaborative Editor: triggered by 'User-visible edit conflicts > 5% of sessions; poll interval '. Streaming Media Platform: triggered by 'Upload API p99 exceeding 30 seconds due to in-process transc'.

Migration Step 2

Realtime Collaborative Editor

Last-write-wins conflict resolution → Operational transformation (OT) or CRDT-based conflict resolution

Streaming Media Platform

Viewing history in PostgreSQL → Viewing history in Cassandra

Both scenarios define a migration step at this stage. Realtime Collaborative Editor: triggered by 'Data loss complaints from users editing simultaneously; conf'. Streaming Media Platform: triggered by 'PostgreSQL viewing history table exceeding 500M rows; write '.

Migration Step 3

Realtime Collaborative Editor

No further migration step defined

Streaming Media Platform

Single CDN provider with no origin rate limiting → Multi-CDN with origin request coalescing and rate limiting

Streaming Media Platform has a defined migration; Realtime Collaborative Editor does not at this stage.

Advisor Notes

Realtime Collaborative Editor

Strength: A connection pool bounds the total database connections an application can open, preventing connection storms during traffic…

A connection pool bounds the total database connections an application can open, preventing connection storms during traffic spikes and protecting the database server from exceeding its connection limit. Key trade-off: Pooler becomes a new single point of failure if not replicated. Operational note: PgBouncer transaction-mode pooling is most effective for stateless APIs. Evidence: PgBouncer reduces PostgreSQL connections by 10–100x in typical deployments.

Realtime Collaborative Editor

Risk (high): Connection Pool Exhaustion

All database connections in the pool are in use; new requests queue and then time out, causing cascading latency and errors across all dependent services.

Streaming Media Platform

Risk (high): Queue Backlog Accumulation

Message queue or event stream consumer processing rate falls below producer write rate, causing consumer lag to grow unboundedly: eventually leading to increased end-to-end latency, producer backpressure, data expiry, or queue resource exhaustion.

Both

Shared Operational Requirements

Both scenarios require: Cache sizing and eviction policy configuration, PostgreSQL: scenario includes high_write_throughput or write_heavy workload, Redis: scenario has read_heavy workload with high cache miss risk.

Confidence Preliminary

Where to Start

Start with Realtime Collaborative Editor

Left

Realtime Collaborative Editor has lower operational complexity. Starting here reduces risk and cognitive load. Migrate to the more capable architecture only when you hit concrete scaling or feature limits.

Complexity: expert complexity, 5 nodes, 2 edges, 1 risks, 1 simulation seeds

Migrate when:

  • Server memory growing with active connections; file descriptor limits approached; new WebSocket connections refused → Increase file descriptor limits (ulimit); move to dedicated WebSocket server tier; implement connection multiplexing (multiple documents per connection where safe)
  • Consecutive writes to the same document causing lock contention; write latency rising; auto-save batching queue depth increasing → Move to operational transformation or CRDT-based conflict resolution; batch writes and resolve conflicts in-process before database commit; consider append-only event log for document operations
  • Redis memory growing; high number of active pub/sub channels per Redis instance; SUBSCRIBE/UNSUBSCRIBE operations becoming significant overhead → Shard Redis pub/sub by document range; implement channel expiry; consider dedicated messaging tier (e.g. Ably, Pusher) for very high session counts

Decision Flow

1

Does your team have the operational maturity to run Realtime Collaborative Editor (expert only rating)?

If Yes

Your team can operate Realtime Collaborative Editor. Continue to Step 2 to refine based on risk tolerance and workload fit.

If No

Prefer the lower-maturity option: right scenario.

Right
2

Is operational stability and minimising production risk your primary concern over feature richness or scalability ceiling?

If Yes

Prefer Realtime Collaborative Editor: it carries lower operational risk weight per the advisor's assessment.

Left

If No

Proceed to Step 3 to evaluate based on scaling requirements.

3

Do you expect your load to reach: Kafka consumer group lag on the transcoding topic growing during peak upload hours; content availability delay > 10 minutes for newly uploaded videos; transcoding worker CPU consistently above 85% across all instances ?

If Yes

Right scenario has more defined scaling evolution paths for this growth pattern.

Right

If No

If you don't expect to hit these scaling signals soon, prefer the simpler architecture and re-evaluate when load patterns become clearer.

4

Does your team already operate an event streaming platform (e.g., Kafka, Kinesis, Pub/Sub) in production?

If Yes

Streaming Media Platform builds on event stream infrastructure. Your existing platform reduces the adoption risk.

Right

If No

If you don't have an event streaming platform, the other scenario avoids adding that infrastructure dependency. Evaluate whether the async decoupling benefit justifies the new ops burden.

Left
5

Is operational simplicity (fewer moving parts, easier debugging, lower ops burden) more important than maximum architectural capability?

If Yes

Realtime Collaborative Editor is the simpler choice: Realtime Collaborative Editor is simpler: expert operational complexity with 5 topology nodes vs 21 for Streaming Media Platform.

Left

If No

If capability and scalability ceiling matter more than simplicity, evaluate the higher-complexity scenario against your specific load model.

When you want to minimise monitoring setup overhead

Moderate

Realtime Collaborative Editor has a lower observability burden: fewer watched metrics and monitoring targets.

When your architecture benefits from: a connection pool bounds the total database connections an application can open, preventing connection storms during traffic…

Moderate

A connection pool bounds the total database connections an application can open, preventing connection storms during traffic spikes and protecting the database server from exceeding its connection limit. Key trade-off: Pooler becomes a new single point of failure if not replicated. Operational note: PgBouncer transaction-mode pooling is most effective for stateless APIs. Evidence: PgBouncer reduces PostgreSQL connections by 10–100x in typical deployments.

Streaming Media Platform

Right

When you need well-defined scaling thresholds and migration paths

High

Streaming Media Platform has more documented scaling evolution steps (4 thresholds, 3 migration paths).

When your team has limited operational maturity

Critical

Streaming Media Platform is rated advanced , accessible for teams without deep platform expertise.

When your system requires decoupled async event processing

High

Streaming Media Platform includes event stream infrastructure (e.g., Kafka/Kinesis), enabling async decoupling between producers and consumers.

When to Avoid Each Scenario

Realtime Collaborative Editor

Left

When your team cannot mitigate: connection pool exhaustion

High

This architecture is significantly exposed to Connection Pool Exhaustion. All database connections in the pool are in use; new requests queue and then time out, causing cascading latency and errors across all dependent services.

When your team does not have platform engineering expertise

Critical

Realtime Collaborative Editor is rated 'expert only'. It requires deep operational expertise to run safely. Operating it without the right team leads to incidents.

When you expect rapid growth within the next 12–18 months

Moderate

The advisor identifies 3 predicted bottlenecks for Realtime Collaborative Editor. Rapid growth will surface these limitations quickly.

Streaming Media Platform

Right

When your team cannot mitigate: queue backlog accumulation

High

This architecture is significantly exposed to Queue Backlog Accumulation. Message queue or event stream consumer processing rate falls below producer write rate, causing consumer lag to grow unboundedly: eventually leading to increased end-to-end latency, producer backpressure, data expiry, or queue resource exhaustion.

When your team cannot mitigate: thundering herd (cache stampede)

High

This architecture is significantly exposed to Thundering Herd (Cache Stampede). When a popular cached key expires or a service recovers from downtime, all requests that were waiting or arrive simultaneously miss the cache and hit the origin database concurrently, producing a request spike that can overwhelm the database within seconds.

When your team is early-stage or solo

High

Streaming Media Platform is rated 'advanced'. It requires experienced backend engineers or platform tooling to operate reliably at scale.

When you expect rapid growth within the next 12–18 months

Moderate

The advisor identifies 9 predicted bottlenecks for Streaming Media Platform. Rapid growth will surface these limitations quickly.

Team Fit

Solo developer or small startup

Right

Streaming Media Platform is more accessible for small teams. Fewer operational moving parts reduces on-call burden.

  • Validate that the simpler architecture can handle your projected load before committing.

Small product team (2–6 engineers)

Right

Streaming Media Platform suits small teams that need to move fast without deep platform tooling investment.

  • Consider Realtime Collaborative Editor only if your workload pattern specifically requires it.

Experienced backend team

Depends

An experienced team can operate either architecture. Choose based on workload fit, not team capability.

  • Prioritise alignment with existing infrastructure and tooling.
  • Realtime Collaborative Editor may require additional runbook coverage and alerting investment.

Platform engineering team or SRE-equipped organisation

Left

A platform team can safely operate Realtime Collaborative Editor and will benefit from its more advanced scaling characteristics.

  • Ensure observability and alerting are configured before launch.

Migration Triggers

Migration Step 3

Streaming Media Platform has a defined migration; Realtime Collaborative Editor does not at this stage.

LeftDependsAct Soon

Server memory growing with active connections; file descriptor limits approached; new WebSocket connections refused

Tier 1: WebSocket Connection Ceiling: WebSocket server process connection limit or OS file descriptor ceiling. Recommended evolution: Increase file descriptor limits (ulimit); move to dedicated WebSocket server tier; implement connection multiplexing (multiple documents per connection where safe) .

LeftDependsAct Soon

Consecutive writes to the same document causing lock contention; write latency rising; auto-save batching queue depth increasing

Tier 2: Database Write Contention: High-frequency auto-save operations conflicting at the document row level; row-level locking under concurrent user edits . Recommended evolution: Move to operational transformation or CRDT-based conflict resolution; batch writes and resolve conflicts in-process before database commit; consider append-only event log for document operations .

RightDependsAct Soon

Kafka consumer group lag on the transcoding topic growing during peak upload hours; content availability delay > 10 minutes for newly uploaded videos; transcoding worker CPU consistently above 85% across all instances

Tier 1: Transcoding Worker Throughput: Transcoding consumer group undersized relative to peak upload volume. Recommended evolution: Increase transcoding consumer instances up to the transcoding topic partition count; tune partition count to match the maximum desired worker parallelism (set this at topic creation, not after lag appears); implement per-uploader upload rate limits to smooth burst input; consider priority queuing so premium-tier content does not wait behind bulk ingest jobs .

RightDependsAct Soon

MinIO GET request rate spikes > 10x baseline immediately after content publish or CDN invalidation; MinIO p99 latency > 500ms; CDN miss ratio > 5% on popular content

Tier 2: CDN Origin Thundering Herd: CDN cache miss storm on first-play of new or recently-updated content. Recommended evolution: Implement origin request coalescing (single origin fetch per CDN node per object, queue subsequent requestors for the in-flight response); pre-warm CDN edges for anticipated high-traffic content before publish; add rate limiting at the origin gateway to cap per-second origin requests per content_id .

Readiness Requirements

Cache sizing and eviction policy configuration

Both

Redis or equivalent cache requires correct maxmemory configuration, eviction policy selection (allkeys-lru is common), and cold-start warming strategy after restarts.

PostgreSQL: scenario includes high_write_throughput or write_heavy workload

Both

Deploy PgBouncer in transaction-mode pooling before relying on vertical scaling

Required maturity: mid_level

Redis: scenario has read_heavy workload with high cache miss risk

Both

Implement cache stampede protection (probabilistic early expiry or locking) to prevent thundering herd on cold start

Required maturity: junior

Redis: scenario relies on Redis for data that cannot be re-derived

Both

Redis is not a durable store: add persistence layer or treat Redis as expendable cache only

Required maturity: junior

Runbooks and alerting for high-severity risks

Both

1 high-severity risk identified. Each requires a documented runbook, alerting threshold, and on-call response procedure before running in production.

Minimum team maturity: Enterprise Architecture Team

Left

This scenario has expert operational complexity. It is recommended for Enterprise Architecture Team teams or higher.

Required maturity: enterprise_architecture_team

Apache Cassandra: scenario has team_maturity below staff_plus

Right

Cassandra has the highest operational complexity of common datastores: consider managed options (Astra DB, Keyspaces) or simpler alternatives

Required maturity: staff_plus

Apache Cassandra: scenario has time_series or iot_telemetry workload

Right

Design partition keys with time-bucketing (e.g., date prefix) to prevent wide partitions as data grows

Required maturity: staff_plus

Apache Cassandra: scenario requires ad-hoc queries or analytics

Right

Cassandra cannot efficiently query non-partition-key dimensions: pair with Elasticsearch or ClickHouse for analytics

Required maturity: staff_plus

Apache Kafka: scenario has team_maturity below senior

Right

Kafka operational complexity requires dedicated expertise: consider MSK or Confluent Cloud to reduce ops burden

Required maturity: senior

Apache Kafka: scenario uses Kafka for event streaming or CDC

Right

Set min.insync.replicas=2 with acks=all; monitor consumer lag as primary health signal

Required maturity: senior

Event stream operations expertise

Right

This architecture includes event stream infrastructure (Kafka, Kinesis, or similar). Operations requires consumer group management, partition assignment, dead-letter handling, and lag monitoring.

Required maturity: platform_engineering_team

MinIO: scenario enables versioning without lifecycle expiration policies

Right

Configure ILM lifecycle policies with expiration rules for versioned objects; without expiration, version accumulation on high-churn objects consumes storage unboundedly

Required maturity: mid_level

MinIO: scenario stores large numbers of small objects (< 100KB average size)

Right

MinIO's per-request overhead reduces effective throughput for small objects; evaluate aggregating small objects into larger archives or using a key-value store for small object access patterns

Required maturity: mid_level

Minimum team maturity: Experienced Backend Team

Right

This scenario has high operational complexity. It is recommended for Experienced Backend Team teams or higher.

Required maturity: experienced_backend_team

Generator Constraints

Realtime Collaborative Editor

Left

Generator relevance documented but not yet production-ready.

When generating architectures for collaborative editing or presence-aware applications, the WebSocket + Redis pub/sub + PostgreSQL composition should be presented as the baseline. CRDT/OT conflict resolution should be surfaced as a required upgrade path before launch in production collaborative contexts. The knowledge base currently lacks detailed CRDT/OT pattern entries: these should be added as the knowledge base expands.

Streaming Media Platform

Right

Generator relevance documented but not yet production-ready.

For content platform briefs with video or audio delivery requirements, the generator should output the Kafka async transcoding pipeline, MinIO object storage, and CDN-first delivery as the canonical composition. Redis playback session with TTL enforcement and Cassandra for time-ordered viewing history should be generated as separate store responsibilities. The generator must flag the partition key design decision for the Cassandra history table as a mandatory architecture decision requiring explicit access pattern enumeration before schema creation.
