1. A computer implemented method of creating a manifest-based snapshot of a data object in a distributed cloud-computing platform, the method comprising:

  • responsive to receiving a request to create a snapshot of the data object,identifying, by a master node of a distributed database system, multiple slave nodes of the distributed database system on which a data object is stored in the cloud-computing platform,wherein the distributed database system includes the master node and the multiple slave nodes,wherein each slave node implements a region server and includes a data node associated with the region server;

    creating a snapshot manifest representing the snapshot of the data object,wherein the snapshot manifest comprises a file including a listing of multiple file names in the snapshot manifest and reference information for locating the multiple files in the distributed database system,wherein creating the snapshot manifest further comprises directing each region server to create a portion of the snapshot manifest corresponding to the partition of the data on the data node with which the region server is associated,wherein directing each region server to create the portion of the snapshot manifest corresponding to the partition of the data on the data node with which the region server is associated comprises;

    generating, by the master node, a request to each region server for the respective portions of the snapshot manifest corresponding to the partition of the data on the data node with which the region servers are associate; and

    sending, by the master node, the requests to the corresponding region servers.
