Restoring partitioned database tables from backup

A system, comprising:

• one or more processors;
• a memory coupled to the one or more processors;
• and
• a plurality of storage nodes, each of which comprises one or more storage devices or logical storage volumes;
• wherein the memory stores program instructions that when executed by the one or more processors cause the one or more processors to implement a distributed database service;
• wherein the distributed database service maintains data for a table in one or more partitions, wherein to maintain the data in the one or more partitions, the distributed database service is configured to store two or more replicas of each of the one or more partitions on respective storage devices or logical storage volumes of respective ones of the plurality of storage nodes;
• wherein the distributed database service is further configured to store one or more configuration parameters values that are associated with the table, wherein the one or more configuration parameter values specify one or more of:
• a provisioned storage capacity for the table, a provisioned storage capacity for one of the one or more partitions, a provisioned throughput capacity for the table, a provisioned throughput capacity for one of the one or more partitions, or an attribute by which items in the table are indexed;
• wherein a request router component of the distributed database service is configured to:
• receive a request to back up the table in a remote storage system;
• wherein in response to the request to back up the table, an administrative component of the distributed database service is configured to upload a copy of each of the one or more partitions to the remote storage system;
• wherein the request router component is further configured to receive a request to restore the table from the remote storage system, wherein the request specifies a value for one of the one or more configuration parameters that is different than the corresponding stored configuration parameter value;
• and
• wherein in response to the request to restore the table, the administrative component is configured to:
• create a new table into which the copies of the one or more partitions are to be restored;
• import the copies of each of the one or more partitions from the remote storage system into the new table such that each of the imported partition copies is stored on a storage device or logical storage volume of one of the plurality of storage nodes;
• and
• apply to the new table the value for the one of the one or more configuration parameters that was specified in the request to restore the table.
