A field team needs more than an offline save button. It needs the information to finish the job. 8DB brings native data operations, protected capture and verifiable delivery into one embeddable database. That creates a practical opportunity: keep the investigation on the device, then reconcile the work when connectivity returns.
The delivery foundation has already been exercised. In a completed local telemetry rehearsal, 8DB captured 16,384 records while disconnected, then delivered them alongside 128 new records. A separate verifier reconciled all 16,512 records, their exact content and signed receipts. A fresh process reopened the stores and confirmed the expected data with no pending deliveries. This was a vendor-run Linux rehearsal using local TCP endpoints and test keys. Rehearsal evidence and scope
For a field-software buyer, the next question is compelling: how much of the work currently spread across a local store, mapping layer and delivery service could your application inherit from one engine?
Start with the work that must continue
Imagine a technician investigating an overheating compressor at a remote site. The application needs to locate the equipment, inspect recent readings, follow the link to its last service and record a new observation. Uploading a form later is only the final step.
8DB is an omnimodal database. Spatial, time-series and graph operations let a developer model those questions in their native structures. The point of bringing them together is to keep the asset's location, measurements and relationships usable within the local application, without assembling a new remote service for each question.
| During the visit | Local operation | Work the integration could remove |
|---|---|---|
| Find the equipment | Select spatial records for the relevant area | A cloud lookup before the investigation can start |
| Understand the alert | Inspect readings linked to the asset and its history | Reconstructing the relationship from separately synchronized copies |
| Record the intervention | Capture a protected observation for later delivery | A separately designed capture-to-delivery handoff |
| Reconnect | Reconcile delivered content and receipts | Guessing whether a sent record was actually applied |
This inspection workflow is an application design built from existing capabilities. The completed telemetry rehearsal establishes its capture-and-delivery foundation; it does not certify the entire compressor application. The native-views example shows how one identity can connect different questions, while the storage evidence records the separate recovery results.
Compare the complete application
Couchbase Lite already offers embedded queries and synchronization. It is a credible choice for offline applications. The reason to evaluate 8DB is the broader combination your particular job can use: native structures, protected records, local operations and recipient-bound delivery.
8DB is built for fieldwork that needs more than document synchronization: location, measurements, relationships and the evidence behind a decision. Compare the complete workflow and the transformations, services and recovery procedures your team would otherwise maintain.
That is the architectural opportunity behind 8DB. Fewer application-owned handoffs can mean fewer places to reconcile data and policy. The size of that saving depends on the application and should be measured in the pilot.
Test the whole outage
The completed rehearsal followed the records beyond transmission to exact-content verification and fresh-process reopening. That is a more useful starting point than a successful local write alone.
The separate public two-workstation recovery record preserves process-kill and same-store-reopen evidence for a different protected profile. Keep those experiments distinct. A customer's acceptance test should extend the relevant path to its device, storage and expected interruption, including physical power loss when required.
Agree what an acknowledgement promises, what happens at capacity, and how the receiver establishes durable application. Those answers determine whether the field team can rely on saved work.
A field task has more than one finish line
Test through the outage, not just at its start.
Agree what must remain usable, retained and recoverable at each stage.
- 01 · Before disconnect
Define the local job
Load the required data, permitted operations and authority state. Agree what an acknowledgement promises.
- 02 · While offline
Keep useful work local
Exercise the real queries and writes. Observe backlog, capacity handling and permission expiry.
- 03 · After interruption
Recover promised state
Check acknowledged records and local operations against the declared restart or failure model.
- 04 · On reconnect
Verify the destination
Refresh authority, reconcile pending work and confirm the receiver's durable result.
Keep authority local and its limits visible
The reviewed protected-node composition can operate in software without a mandatory cloud key-service call. It creates recipient-specific protected messages, checks authority at receiver admission and durable application, then seals received records under the receiver's own root. Useful local operations and controlled delivery can therefore share an engine boundary.
A disconnected device enforces the authority state it has. Remote revocation reaches it only when communication permits. Define which actions remain available and when authority must be refreshed. Endpoint secrets, provisioning and recovery material also need custody; the local-protection guide explains those choices.
Choose the field workflow that matters first: useful local queries, protected exchange or disconnected telemetry delivery. Then bring those components together around your schema and target devices.
Make your first evaluation a working visit
Start with one task that loses value when connectivity disappears. A non-sensitive description of the device, information needed and expected outage is enough for an initial discussion. We can map the local operations and delivery boundary, identify what 8DB already supplies, and define the smallest demonstration that would settle fit.
Show us the task your field team needs to finish offline. The first useful output is a workflow map: what stays local, what reconnects, and which application handoffs you could stop maintaining.
