Abstract

Techniques are described herein for efficiently and expeditiously performing key rotation and key replacement. In an embodiment, a key replacement request is received that specifies one or more key names of a plurality of key names. A location-to-key-name mapping that maps the plurality of key names to a plurality of encrypted-data locations is used to determine one or more encrypted-data locations that are mapped to the one or more key names. A first set of messages is generated where each message identifies a table that is associated with the one or more encrypted-data locations. The first set of messages is stored in a queue for processing by a first plurality of worker processes. Each worker process of the first plurality of worker processes retrieves a message of the first set of messages from the queue and generates a message of a second set of messages that identifies a subset of encrypted data records from the table identified in the message of the first set of messages. Each message of the second set of messages is stored in a distinct queue which is assigned to a worker process of a second plurality of worker processes. Each worker process of the second plurality of worke…
