HERE Volatile Blob API v1

HERE Volatile Blob API v1 — 5 operation(s) across 1 path(s), OpenAPI 3.0.1 version 1.0.3, harvested verbatim from the HERE developer documentation. The volatile-blob service supports the upload and retrieval of volatile data from the storage of a catalog. Each discrete chunk of data is stored as a blob (Binary Large Object). Each blob has its own unique id (data handle) which is stored as partition metadata. To get a partition's data, you first use metadata service to retrieve the partition's metadata (data handle) with the addresses of the relevant blobs. You then use those addresses to pull the data using the volatile-blob service. Unlike the blob service, data handles can be overwritten. Hence the volatile aspect. Base URL is not fixed: the spec directs clients to resolve it at runtime through the HERE API Lookup Service (https://api-lookup.data.api.platform.here.com/lookup/v1).

Operations 5

GET /layers/{layerId}/data/{dataHandle} Gets a volatile blob #
HEAD /layers/{layerId}/data/{dataHandle} Checks if a data handle exists #
PATCH /layers/{layerId}/data/{dataHandle} Modifies ttl for a specific volatile data blob #
PUT /layers/{layerId}/data/{dataHandle} Publishes a volatile data blob #
DELETE /layers/{layerId}/data/{dataHandle} Deletes a volatile data blob #
