Abstract
Methods and systems for selectively encrypting commit log entries in a distributed database system are described. One example method includes determining that a commit log for a particular server in the distributed database system is to be updated based on a data operation performed on a tablet managed by the server, the tablet including at least a portion of the data from a table in the distributed database system, and wherein the data from the table is stored in multiple tablets; determining that the tablet managed by the particular server is an encrypted tablet; in response to determining that the tablet is an encrypted tablet, generating an encrypted log entry representing the data operation performed on the tablet including an encrypted payload including information representing the data operation and an unencrypted header including information about the encrypted log entry; and updating the commit log to include the encrypted log entry.
