Abstract
Provided are systems and methods for storing checkpoints of an in-memory storage device. In one example, the method may include detecting database transactions performed on a slice of an in-memory storage and storing a record of the database transactions in a log file, receiving a request to persist the slice of in-memory storage, the request comprising a timing indicator corresponding to a timing of database transactions, trimming the log file based on the timing indicator to remove a record of one or more database transactions from the log file that occurred prior to the timing indicator and to preserve a record of one or more database transactions that occurred after the timing indicator, and persisting, to disk, data from the slice of in-memory storage and the trimmed log file preserving the record of the one or more database transactions that occurred after the timing indicator.
