Use when you need framework-agnostic MongoDB and non-relational database query guidance — document schema design, collection modeling, JSON Schema validation, indexes, aggregation pipelines, query performance, consistency trade-offs, transactions, and operational safety — without choosing Spring Boot, Quarkus, or Micronaut. This should trigger for requests such as Design MongoDB document schemas; Review MongoDB queries and indexes; Improve aggregation pipeline performance; Model non-relational…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Non-relational database query best practices Help teams design maintainable, secure, and performant **MongoDB and non-relational database queries** for Java applications. **What is covered in this Skill?** - Document modeling for aggregates, embedded documents, references, arrays, and bounded growth - MongoDB JSON Schema validation and compatibility-aware schema evolution - Query design: explicit predicates, projections, sort stability, pagination, collation, and read concerns - Index strategy: compound indexes, covering queries, partial indexes, TTL indexes, unique constraints, and lifecycle review - Aggregation pipelines: stage ordering, `$match` pushdown, `$project`, `$lookup`, `$unwind`, `$group`, and memory controls - Consistency, transactions, idempotency, migration safety, testing, observability, and production diagnostics **Scope:** Framework-agnostic MongoDB and non-relational data modeling. For Java framework integrations, defer to the matching Spring Boot, Quarkus, or Micronaut MongoDB skill. ## Constraints …

How to install
mdr add jabrena/plinth/705-technologies-nosql-mongodb@sha256:9662f405f966a6bbThe line at the top of this page pins the label v0.19.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
