A method of maintaining a data store is disclosed. The data store is distributed across a plurality of storage provider instances, including a master storage provider instance and a plurality of additional storage provider instances. A master data log is updated to reflect a change to the data store. The master data log is synchronized with a plurality of replicas of the master data log. The change is propagated across the plurality of additional storage provider instances based on an analysis of the replicas.

A multi-tenancy storage node is provided. The storage node hosts partitions of multiple databases accessed by multiple applications. Each database is governed by a corresponding service-level agreement (SLA) or policy that specifies a maximum load or level of operation of the database in terms of one or more metrics (e.g., number or frequency of reads/writes, maximum size of reads/writes). To determine whether another database can be hosted by the node, a snapshot of the node's database operations is replayed on a test node, along with operations that exercise the other database. If maximum thresholds of the node for the metrics are not exceeded, the other database can be added to the storage node. An SLA is generated for it automatically, based on the metrics it exhibited during the operations on the test node. The storage node may enforce the SLA by rate-limiting activity of one or more applications.
