  • Patent number: 11210169
    Abstract: Data storage method, apparatus, and system are disclosed. The data storage method includes: encoding a data block using an erasure coding to obtain corresponding multiple data fragments; separately writing the multiple data fragments to corresponding allocated storage nodes; and determining that writing of the data block is successful if a number of storage nodes to which data fragments is successfully written within a first defined time duration is greater than or equal to a defined value, wherein the defined value is greater than or equal to a number of data block fragments in the multiple data fragments and is less than or equal to a number of the multiple data fragments. As such, the latency of a data write can be reduced, and the performance stability can be improved when a storage node encounters a failure.
