Abstract
A data storage system may implement implicit prioritization to rate-limit secondary index creation for an online table. A secondary index may be generated for a table stored in a data store. The table may be incrementally indexed, performing multiple indexing operations to populate the secondary index. Prior to performing an indexing operation, an evaluation of a capacity limitation for performing indexing operations may be made with respect to capacity to process access requests at the data store. If a determination is made that performance of the indexing operation exceeds the capacity limitation, then the indexing operation may be throttled. If a determination is made that performance of the indexing operation does not exceed the capacity limitation, then the indexing operation may be performed.
