Abstract
The present application relates to database management in a cloud environment. A compute service generates a transaction log for database actions. The compute service writes at least a first portion of the transaction log to a log replica service. The log replica service replicates at least the first portion of the transaction log to two or more local log replicas persisted on solid state drives. A page server service updates database data in a remote storage based on at least a second portion of the transaction log retrieved from at least one of the log replicas. The page server service moves at least the second portion of the transaction log to the remote storage. The log replica service truncates the local log replicas by purging the second portion.
