Independent ClickHouse OSS 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. Commercial ClickHouse offerings are separately covered under Strategic Partners.
WHY IT MATTERS
ClickHouse OSS provides a powerful analytical engine that can be self-managed where operations teams need control of topology, infrastructure and data.
As a column-oriented database, ClickHouse is designed for high-volume event analysis, aggregations over large tables and analytical APIs. Self-managing it gives you full control over where data lives, how clusters are sized and when upgrades happen. It also means your team owns sharding, replication, coordination, merges, backups and upgrades. Those are the areas where production deployments succeed or struggle, and where Bassirah focuses.
WHAT BASSIRAH DELIVERS
ENGINEERING FOCUS
Choose sharding keys that spread data and queries evenly, and replicate shards with replicated table engines so the loss of one node does not lose data or availability.
Run a dedicated Keeper ensemble, typically an odd number of nodes, to coordinate replication and distributed DDL. Keeper health directly affects write availability.
Design batch sizes, asynchronous inserts or streaming ingestion so the engine creates manageable data parts and background merges keep up.
Select primary keys, ordering, partitioning, codecs, TTL rules and materialized views around your query patterns and retention policy.
USE CASES
Dashboards and investigations over fresh event data, served at workload-appropriate latency.
High-volume observability and telemetry data with retention tiers and compression designed for cost control.
Low-latency analytics APIs and warehouse acceleration, offloading heavy analytical queries from transactional or legacy systems.
We will profile it and prioritize fixes.
RESILIENCE
We design availability per failure domain and prove recovery with restore tests, against RTO and RPO you approve.
| Failure domain | Design pattern | How we validate |
|---|---|---|
| Single replica node | Replicated tables with at least two replicas per shard; load balancing across replicas | Node loss under load; replication catch-up monitoring |
| Keeper ensemble | Odd-numbered Keeper ensemble on separate failure domains, with its own monitoring | Keeper node loss test; quorum loss runbook |
| Data corruption or human error | Scheduled backups to separate storage, plus documented restore and partition-level recovery | Restore drill into an isolated environment |
| Site or region | Replicas or backups in a second site, with DNS or application-level switchover | Documented failover and failback drill |
Bassirah does not produce official ClickHouse releases or security fixes. We assess, test and roll out upstream releases on your behalf. Related: HA/DR & Platform Reliability.
TWO ROUTES, ONE TECHNOLOGY
ClickHouse appears in both Bassirah portfolios because there are two different procurement and support routes into related technology: independent engineering services for the open-source edition, and partner-led ClickHouse solutions. Architecture and available features depend on the selected deployment and entitlement. We help you choose based on control, capability and support requirements.
| Decision factor | ClickHouse OSS (independent support) | Partner-led ClickHouse (Strategic Partner) |
|---|---|---|
| Software | Community edition under an open-source license | Commercial ClickHouse offerings, subject to contract |
| Deployment and control | Self-managed on infrastructure you choose; you control topology, data location and upgrade timing | Deployment options as offered under the commercial program, which may include vendor-managed services |
| Feature availability | Community-edition features of the release you run | Features depend on the selected offering and entitlement; some capabilities may differ from the community edition |
| Upstream support | Community channels; Bassirah contractual engineering support | Vendor-backed support per contract, plus Bassirah services |
| Operations | Your team and/or Bassirah operate the cluster, per agreed support scope | Operational responsibilities shared with the vendor per the selected offering |
| Upgrade management | Customer/Bassirah validation of release choice and compatibility | Vendor release and support lifecycle according to contract |
| Cost profile | No license fee; budget for infrastructure, engineering and operations | Subscription or consumption fees plus implementation services |
| Selection rule | Choose when self-management meets your control, security and operating objectives | Choose when commercial assurances, managed operations or licensed capabilities justify it |
No feature promises across routes.
We do not assume that a capability available in a commercial ClickHouse offering is available in the community edition, or the reverse. We confirm features, versions and support entitlements for the exact deployment you choose.
You want full control of infrastructure and data, your workloads fit community-edition capabilities, and you are ready to own operations with Bassirah’s support.
You want vendor-backed support, commercial capabilities or vendor-managed operations, with Bassirah handling architecture, integration and data modeling.
WORKS WITH
Integrate dbt, DataHub and Redis based on workload and compatibility.
Low-latency serving, caching and application state alongside ClickHouse analytical history, where measurements justify it.
SQL transformations on ClickHouse where the current adapter supports your required features.
Metadata, ownership and lineage for ClickHouse databases and tables.
The end-to-end solution pattern from event ingestion to analytical serving.
They represent two procurement and support routes into related technology: partner-led ClickHouse solutions and independent engineering services for the OSS edition. Architecture and available features depend on the selected deployment and entitlement.
No. Our ClickHouse OSS services are independent engineering and support. Vendor-backed support applies only where separately covered by a commercial agreement, which we can discuss through our partner-led route.
Replicated ClickHouse deployments need a coordination service. ClickHouse Keeper is the project’s own coordination service and is the usual choice for new deployments. We plan the Keeper ensemble, or a migration from an existing ZooKeeper setup, as part of the cluster design.
We design backups to separate storage using the backup mechanisms available in your release, define retention, and run restore drills into an isolated environment. Replication protects availability. It does not replace backups, because errors and deletions replicate too.
Yes. We assess feature, version and data compatibility, plan the migration path and validate the result. The right route depends on your control, capability and support requirements.
Tell us about your data volumes, query patterns and operating model. We will scope a readiness assessment and a practical next step.
