Serverless managed bulk import on a global NoSQL database with selective back pressure

A method, comprising:

• receiving a request to import one or more data files from a source data store into a target database;
• responsive to the request:
• reserving a first portion of computing resources that host the target database to import the one or more data files, wherein the reservation of the first portion of computing resources permits the import throughput rate of the one or more data files through the first portion of computing resources while maintaining a second portion of the computing resources to support client access to the target database at an access throughput rate;
• and
• initiating import of the one or more data files from the source data store to the target database through one or more storage nodes at the import throughput rate according to the first portion of computing resources, wherein the target database is able to receive access requests from one or more clients during the import of the one or more data files to the target database.

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

• receiving a request to import one or more data files from a source data store into a target database;
• responsive to the request:
• reserving a first portion of computing resources that host the target database to import the one or more data files, wherein the reservation of the first portion of computing resources permits the import throughput rate of the one or more data files through the first portion of computing resources while maintaining a second portion of the computing resources to support client access to the target database at an access throughput rate;
• and
• initiating import of the one or more data files from the source data store to the target database through one or more storage nodes at the import throughput rate according to the first portion of computing resources, wherein the target database is able to receive access requests from one or more clients during the import of the one or more data files to the target database.
