System and method for multiqueued access to cloud storage
Systems and methods are disclosed herein for multithreaded access to cloud storage. An exemplary method comprises creating a plurality of mount points by mounting, by a hardware processor, a plurality of file systems on a computer system, creating an image file on each of the plurality of mount points, instantiating, for each of the plurality of mount points, a block device on the image file, creating a union virtual block device that creates one or more stripes from each block device, delegating a request for accessing the union virtual block device, received from a client, to one or more block devices and merging a result of the request from each of the one or more block devices and providing the result to the client.
1. A method for multiqueued access to cloud storage comprising:
creating a plurality of mount points by mounting, by a hardware processor, a plurality of file systems on a computer system;
creating an image file on each of the plurality of mount points;
instantiating, for each of the plurality of mount points, a block device on the image file;
creating a union virtual block device that creates one or more stripes from each block device;
receiving, from a client, a request for accessing the union virtual block device;
splitting the request, when the request is larger than a predetermined threshold, into multiple requests;
delegating the multiple requests to a plurality of block devices;
merging a result of the multiple requests from each of the plurality of block devices and providing the result to the client.
2. The method of claim 1 , wherein the client is a file system of a virtual execution environment, and the virtual execution environment is a container or a virtual machine.
3. The method of claim 1 , wherein the client is a virtual machine, and a virtual machine disk image for the virtual machine is stored on the cloud storage.
4. The method of claim 1 , wherein the plurality of file systems are user space file systems.
5. The method of claim 4 , wherein each user space file system is a cloud file system.
6. The method of claim 1 , wherein the image file is in one of a raw format, or an expanding format, wherein the expanding format is qcow2.
7. The method of claim 1 , wherein the union virtual block device is one of a raid-stripe, or raid-N.
8. The method of claim 1 , wherein the computer system is one or more of a chunk server or a metadata server.
9. A system for multiqueued access to cloud storage comprising:
a hardware processor configured to:
create a plurality of mount points by mounting a plurality of file systems on a computer system;
create an image file on each of the plurality of mount points;
instantiate, for each of the plurality of mount points, a block device on the image file;
create a union virtual block device that creates one or more stripes from each block device;
receive, from a client, a request for accessing the union virtual block device;
split the request, when the request is larger than a predetermined threshold, into multiple requests;
delegate the multiple requests to a plurality of block devices;
merge a result of the multiple requests from each of the plurality of block devices and providing the result to the client.
10. The system of claim 9 , wherein the client is a file system of a virtual execution environment, and the virtual execution environment is a container or a virtual machine.
11. The system of claim 9 , wherein the client is a virtual machine, and a virtual machine disk image for the virtual machine is stored on the cloud storage.
12. The system of claim 9 , wherein the plurality of file systems are user space file systems.
13. The system of claim 12 , wherein each user space file system is a cloud file system.
14. The system of claim 9 , wherein the image file is in one of a raw format, or an expanding format, wherein the expanding format is qcow2.
15. The system of claim 9 , wherein the union virtual block device is one of a raid-stripe, or raid-N.
16. The system of claim 9 , wherein the computer system is one or more of a chunk server or a metadata server.
17. A non-transitory computer-readable medium, storing instructions thereon for multiqueued access to cloud storage, the instructions comprising:
creating a plurality of mount points by mounting a plurality of file systems on a computer system;
creating an image file on each of the plurality of mount points;
instantiating, for each of the plurality of mount points, a block device on the image file;
creating a union virtual block device that creates one or more stripes from each block device;
receiving, from a client, a request for accessing the union virtual block device;
splitting the request, when the request is larger than a predetermined threshold, into multiple requests;
delegating the multiple requests to a plurality of block devices;
merging a result of the multiple requests from each of the plurality of block devices and providing the result to the client.
