Abstract: A tiering service enables a client to custom specify service level agreements for data items to be tiered and automatically promotes and demotes the data items amongst a warm tier, a plurality of intermediate tiers, and a cold tier to ensure the service level agreement commitments are met. In some embodiments, a client specifies segmentation criteria for defining multiple segments of data items included in a data scope or table and assigns latency targets to the segments in order to define the service level agreement. Also, in some embodiments, a plurality of intermediate tiers are implemented on common underlying hardware by varying metadata management to implement intermediate tiers that have progressively increasing latencies.

Abstract: Technology is described for data archiving in a service provider environment. A first archive data package may be received from an archival data store in the service provider environment. The first archive data package may include first data blocks and first key block data. Second data blocks and second key block data may be received from a source data store in the service provider environment. Merged data blocks may be created by combining the first data blocks with the second data blocks. The merged data blocks may be sent to the archival data store while merged key block data is being created. The merged data blocks and the merged key block data may be included in a second archive data package that is stored at the archival data store.
