Postgres Connection PoolingAChoosing a Postgres connection pool mode that matches your workload — pgBouncer session/transaction/statement modes, the prepared-statement story (pgBouncer 1.21+), Supabase Supavisor's port-per-mode pattern (5432 vs 6543), AWS RDS Proxy pinning triggers, and `pg_stat_activity` diagnostics. Grounded in pgbouncer.org, supabase.com, AWS docs, and PostgreSQL docs. NOT for ORM-specific connection config, Postgres replication/read-replica design, non-Postgres poolers (PgPool for MySQL, ProxySQL), ...databasespythongoVotes: 0GitHub stars: 2
Outbox Pattern ImplementationAUse when you need to publish a message to Kafka / RabbitMQ / SNS atomically with a database commit, when fixing the dual-write hazard between DB and broker, deciding between polling-publisher and CDC (Debezium) relay, designing the outbox schema, handling at-least-once / idempotency on the consumer, or pruning a high-volume outbox table. Triggers: dual write, "we updated the DB but the event never published", outbox/inbox pattern, Debezium connector, EventRouter SMT, aggregate_type / aggregat...databasesrustgoVotes: 0GitHub stars: 2
Multi Agent CoordinationACoordinate multiple AI agents working on the same codebase or project simultaneously. Covers git worktree isolation, file locking strategies, message passing between agents, shared state management, conflict resolution, task decomposition for parallel agents, and patterns from Claude Code, Cursor, Devin, and similar multi-agent developer tools. Activate on: "multi-agent", "parallel agents", "agent coordination", "worktree isolation", "concurrent agents", "file locking agents", "agent conflict...databasesgobashVotes: 0GitHub stars: 2
Duckdb AnalyticsAUse when running analytical SQL over Parquet/CSV/JSON without a warehouse, replacing pandas for data wrangling, joining S3 data in-place, building local data marts, or embedding OLAP into an app. Triggers: read_parquet/read_csv setup, partitioned dataset queries, hive partitioning, glob patterns for S3, COPY TO export, attach Postgres/MySQL, UDFs in Python/R, MotherDuck cloud sync, columnar performance vs row stores. NOT for OLTP workloads (concurrent writes), distributed analytics at petabyt...databasespythongoVotes: 0GitHub stars: 2
Distributed Tracing W3c ContextAImplementing distributed tracing with W3C Trace Context — the byte-precise `traceparent` and `tracestate` header formats, OpenTelemetry's W3CTraceContextPropagator as the modern default (replacing X-B3-* and X-Datadog-*), head vs tail sampling, and HTTP→SQL trace propagation via sqlcommenter. Grounded in the W3C REC and OpenTelemetry specs. NOT for OTel metrics/logs pipelines, vendor backend setup (Datadog/Honeycomb/Jaeger/Tempo), or browser RUM tracing.databasesgobashVotes: 0GitHub stars: 2
Db Retention And CompactionADesigns and audits data retention and file compaction for an embedded SQLite datastore in a long-lived service — a unified retention registry (one declared policy per table), TTL / absolute-age / row-count-cap policies, a fail-loud coverage guard, WAL/checkpoint tuning, and auto_vacuum/incremental-vacuum so pruning actually shrinks the file. Use when a SQLite DB grows unbounded, a table has an index but no DELETE, a pruned DB never shrinks on disk, metrics are stored as raw events forever, or...databasespythongoVotes: 0GitHub stars: 2
D1 And Supabase MigrationsAUse when applying Cloudflare D1 migrations, fighting Supabase migration history vs SQL execution, choosing direct psql over CLI, designing idempotent migrations, debugging schema drift between local and remote, or recovering after a half-applied migration. Triggers: supabase migration repair instructions appearing, table missing after "applied" status, "Tenant or user not found" when running psql, --remote vs --local D1 confusion, NOT NULL on a populated column, foreign key constraint failure...databasesrustgoVotes: 0GitHub stars: 2
