Abstract
In response to determining that a secondary index is to be created for a particular table of a non-relational database service, a service component verifies that automated transmission of change records of the table to a log-structured journal has been configured. A given change record comprises a before-image and an after-image associated with a committed database write, and is assigned a unique sequence number. A change record propagator for the secondary index examines change records stored in the journal, and transmits selected change records to an index storage node. The index storage node builds the secondary index using the selected change records.
