The online store provides support for materializing feature values within a Rockset collection in order to serve features in real-time.
Each document is uniquely identified by its '_id' value. Repeated inserts into the same document '_id' will result in an upsert.
Rockset indexes all columns allowing for quick per feature look up and also allows for a dynamic typed schema that can change based on any new requirements. API Keys can be found in the Rockset console. You can also find host urls on the same tab by clicking "View Region Endpoint Urls".
Data Model Used Per Doc
{
"_id": (STRING) Unique Identifier for the feature document.
<key_name>: (STRING) Feature Values Mapped by Feature Name. Feature
values stored as a serialized hex string.
