Availability depends on your product, plan and agreement. See the documentation below for the requirements of each route.

ECONOMIC ACCESS

Cost, authentication and limits

Minimum plan and exact route fees remain unconfirmed.

Check API entitlement, credential ownership and rate limits for the route you intend to use. Include review fees, customer-plan upgrades and ongoing access charges in the total.

ACT FROM OUTSIDE

External action

SET writes string values and supports expiry and conditional options. Other Redis data types are outside this scope.

Validate the supported operation, acting identity and permission scope (read access does not imply write permission). Ambiguous retries and revoked credentials also affect whether an external workflow can run safely.

KEEP ACCESS USEFUL

Continuity

Repeat SCAN plus GET for current state. Concurrent changes and expiring keys mean a scan is not a consistent backup or retained event stream.

Useful ongoing access includes corrections and deletions, not only the first export. A failed request, changed filter or lost resource permission should not be interpreted as a deleted record.

LEAVE WITH YOUR DATA

Data exit and portability

Retain selected key/value records and separately record expiry where needed. SCAN plus GET alone does not preserve every type, TTL or complete database state.

Test the output against the destination’s required fields and history. Check stable identifiers, relationships, attachments and extraction time; a sample file proves only the coverage of that sample.

BUILD / INSPECT / REUSE

Business logic and customization

Customers can write external integration code. Native workflow rights and independent execution remain unresolved (record access does not establish portable application logic).

Custom API access, ownership of workflows and the right to export their definitions are separate questions. A custom-app capability alone does not establish that business rules can move to another system.
