MONGODB COMMUNITY SERVER · SOURCE-AVAILABLE (SSPL)
Design and operate MongoDB Community Server for appropriate document-oriented workloads with clear licensing, security and operational guardrails.
Licensing.
MongoDB Community Server is source-available under the Server Side Public License (SSPL) for releases since October 2018. The SSPL is not an OSI-approved open-source license. We include MongoDB Community under our broader “Open-Source & Community Support” category, and we review licensing for your deployment and use case as part of every engagement. This is not legal advice; your legal team should confirm that your intended use complies with the license.
Independent MongoDB Community engineering.
These are independent Bassirah engineering and support offerings. They do not imply upstream vendor or foundation endorsement, official vendor support rights, enterprise feature entitlement or maintenance guarantees.
WHY IT MATTERS
Document flexibility helps evolving applications, but schema, query patterns, consistency, indexing and cluster operations require deliberate design.
Flexible schemas let teams ship features without database migrations for every change. Without design discipline, the same flexibility produces unbounded documents, missing indexes, poorly chosen shard keys and inconsistent read and write guarantees. Bassirah brings data modeling, cluster engineering and operational practice to MongoDB Community deployments so they stay reliable as applications grow.
MongoDB is also one of Bassirah’s strategic technology partners. Compare the partner-led route with independent Community Server support.
WHAT BASSIRAH DELIVERS
ENGINEERING FOCUS
Model documents around access patterns: what to embed, what to reference, and how to keep document size bounded. Add schema validation where data quality matters.
Build indexes from real query shapes, verify plans, and remove indexes that cost writes without serving reads.
Choose shard keys for even distribution and targeted queries, and decide early whether sharding is needed at all.
RESILIENCE
We design availability, backup and security for each deployment and prove recovery against RTO and RPO you approve. See HA/DR & Platform Reliability.
| Scenario | Design pattern | How we validate |
|---|---|---|
| Primary node failure | Replica set with an odd number of voting members across failure domains, so a new primary can be elected; drivers configured for retryable operations | Controlled step-down and node-loss drills |
| Data loss on acknowledged writes | Write concern chosen per data class so critical writes are acknowledged by a majority | Review of application write paths and failover tests |
| Accidental deletion or corruption | Scheduled backups with a consistent method suited to your topology, stored separately | Restore drill into an isolated environment |
| Site or region loss | Replica set members or backups in a second site, with documented recovery steps | Site failover and recovery exercise |
We will test it with you.
KNOW THE EDITION
Some capabilities are available only in commercial MongoDB editions or services. We map your requirements to the edition you run before design starts, so there are no surprises in security reviews or audits.
Independent Community Server support does not include commercial MongoDB features, vendor support or vendor security fixes. If a requirement needs MongoDB Atlas or MongoDB Enterprise Advanced, Bassirah can deliver it through our partner-led route, with vendor support provided under your MongoDB subscription.

USE CASES
Application document data and evolving domain models where flexible schemas speed delivery.
Content and event-oriented operational systems with varied document shapes.
Operational records exposed to analytical query layers without overloading the primary.
WORKS WITH
Trino can query supported MongoDB collections via its connector. DataHub metadata support must be confirmed per release. PostgreSQL and Cassandra are alternatives for different consistency and scale patterns.
Query supported MongoDB collections alongside relational and lakehouse data.
A relational alternative where strong relational constraints and SQL fit better.
A distributed alternative for high-ingest, multi-datacenter patterns.
Contracted operations and incident handling for MongoDB Community estates.
MongoDB Community Server is source-available under the Server Side Public License for modern releases. It is included under the broader “Open-Source & Community Support” website category rather than labeled an OSI-approved open-source product.
It depends on how you use and distribute it. The SSPL places specific conditions on offering the software as a service. Your legal team should review your intended use; we include a licensing review in our engagements to surface questions early.
No. Our services are independent engineering and support for MongoDB Community Server. Vendor support and commercial features require a separate agreement with the vendor.
Not always. Many workloads run well on a well-sized replica set. We assess data volume, write throughput and growth before recommending sharding, because a poor shard key is hard to change later.
Trino provides a MongoDB connector that can query supported collections with SQL. We validate data types, performance and load on the operational cluster before recommending that path.
Tell us about your workloads, topology and licensing questions. We will scope an architecture review and a practical next step.
