US 2025/0028689 A1 · PARTIAL LAYOUT COMMIT

Abstract

Partial commits of file layouts can be performed and managed. In response to a file layout request from a client device (CD), a server can communicate, to CD, first extent list data, comprising a first mapping of a group of blocks, in a data store of the server, to which CD is able to write data to the file. CD can write, and track the writing of, data to first blocks, but not second blocks, of the group of blocks. CD can generate second extent list data comprising a second mapping of the first blocks in the data store to which data is written. CD can communicate a partial commit request, comprising the second extent list data, to the server. In response to the partial commit request, the server can commit the second mapping relating to the first blocks to the data store.

Dependent claims

A method, comprising:

in response to a request to obtain a file layout relating to a file from a client device, communicating, by a system comprising a processor, first extent list information to the client device, wherein the first extent list information comprises a first mapping of a group of blocks in a data store of a server, and wherein the client device is able to write data associated with the file to the group of blocks in the data store;
and
in response to a commit request to have a partial commit of the file layout performed, performing, by the system, a partial commit operation to commit, to the data store, mapping information relating to a second mapping that indicates a subgroup of blocks of the group of blocks in the data store to which the client device has written the data based on second extent list information, comprising the mapping information, that is received from the client device in connection with the commit request.

A client device, comprising:

a memory that stores computer executable components;
and
a processor that executes computer executable components stored in the memory, wherein the computer executable components comprise:
a write component that writes respective items of data to respective first storage locations in a data store of a server based on first extent list data comprising a first mapping of a group of storage locations in the data store of the server, wherein the write component is able to write the respective items of data associated with a file to the group of storage locations in the data store, and wherein the group of storage locations comprises the respective first storage locations and respective second storage locations;
and
a commit requestor component that communicates, to the server, a commit request, comprising second extent list data, that requests the server to perform a partial commit operation to commit a second mapping that indicates the respective first storage locations in the data store to which the write component has written the data based on the second extent list data comprising the second mapping.

3 more elements

A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:

in response to a request to obtain a file layout relating to a file from a client device, transmitting first extent list information to the client device, wherein the first extent list information comprises a first mapping of a group of storage locations in a data store of a server, and wherein the group of storage locations in the data store is usable by the client device to write data to the file;
and
in response to a commit request to have a partial commit of the file layout performed, performing a partial commit operation to commit, to the data store, a second mapping that indicates a first subgroup of storage locations of the group of storage locations in the data store to which the client device has written the data based on second extent list information, comprising the second mapping, that is received from the client device in connection with the commit request, wherein the group of storage locations comprises the first subgroup of storage locations and a second subgroup of storage locations.
