Kind Code:
A1
Abstract:
The present application discloses a data storage method, an apparatus and a system; the data storage method above comprises: performing erasure coding and encoding on a data block, so as to obtain a corresponding plurality of data fragments; writing the plurality of data fragments into the corresponding allocated storage nodes respectively; if the number of storage nodes, into which the data fragment are successfully written within a first set time, is greater than or equal to a set value, determining that the data block is written successfully, the set value being greater than or equal to the number of data block fragments in the data fragments and less than or equal to the number of data fragments. In this way, the data writing delay can be reduced, and the performance stability when a storage node fails can be improved.
