Abstract
Embodiments of the present invention relate to systems, methods and computer storage media for erasure coding data in a distributed computing environment. A sealed extent is identified that is comprised of two or more data blocks and two or more index blocks. The sealed extent is optimized for erasure coding by grouping the two or more data blocks within the optimized sealed extent together and grouping the two or more index blocks within the optimized sealed extent together. The optimized extent may also be erasure coded, which includes creating data fragments and coding fragments. The data fragments and the coding fragments may also be stored in the distributed computing environment. Additional embodiments include monitoring statistical information to determine if replication, erasure coding or a hybrid storage plan should be utilized.
