Data storage system with separate interfaces for bulk data ingestion and data access

A system comprising:

• a plurality of resource hosts configured to store datasets for clients of a data storage system;
• one or more computing devices configured to implement an access interface for the data storage system, wherein the access interface is configured to:
• receive access requests from respective ones of the clients of the data storage system;
• and
• route the requests to respective ones of the resource hosts based on one or more partition maps available to a routing layer of the access interface;
• and
• one or more computing devices configured to implement a bulk ingestion interface for the data storage system, wherein the bulk ingestion interface is configured to:
• ingest bulk data received from a give one of the clients, wherein the ingested bulk data is stored on two or more of the resource hosts of the data storage system;
• and
• determine a new partition map that includes the ingested bulk data for one or more of the given client's datasets;
• wherein the routing layer is configured to:
• receive an indication of the new partition map from the bulk ingestion interface;
• store the new partition map, while continuing to route requests received from the given client based on one of one or more partitions maps previously stored;
• and
• switch routing of subsequent requests received from the given client, in response to receiving a flip over instruction, such that the subsequent requests are routed based on the new partition map for the one or more datasets of the given client.

A method, comprising:

• routing access requests from a client of a data storage system based on one or more partition maps available to a routing layer of an access interface of the data storage system;
• ingesting bulk data received from the client via a bulk ingestion interface of the data storage system to be stored on one or more of resource hosts of the data storage system;
• determining a new partition map that includes the ingested bulk data;
• and
• providing a flip over instruction to the routing layer to switch routing of subsequent requests based on the new partition map.

One or more non-transitory, computer readable media, storing program instructions that when executed on or across one or more computing devices, cause the one or more computing devices to implement:

• routing access requests from a client of a data storage system based on one or more partition maps available to a routing layer of an access interface of the data storage system;
• ingesting bulk data received from the client via a bulk ingestion interface of the data storage system to be stored on one or more of resource hosts of the data storage system;
• determining a new partition map that includes the ingested bulk data;
• and
• providing a flip over instruction to the routing layer to switch routing of subsequent requests from the client based on the new partition map.
