Creating a highly available data analytics pipeline without replicas
Providing for high availability in a data analytics pipeline without replicas, including: creating a data analytics pipeline, wherein each component of the data analytics pipeline is deployed within a container; creating a failover container; detecting that a component within the data analytics pipeline has failed; and responsive to detecting that the component within the data analytics pipeline has failed, deploying the component within the data analytics pipeline that has failed in the failover container.
1. A method comprising:
creating a data analytics pipeline, having a component that is deployed within a container, wherein the container executes in a container cluster that is external to shared storage accessible by components of the data analytics pipeline;
creating a failover container, wherein the failover container is configured to support at least one of components of the data analytics pipeline;
responsive to detecting that a component within the data analytics pipeline has failed, deploying the component that has failed in the failover container;
removing the failed component from the data analytics pipeline; and
adding the component contained in the failover container to the data analytics pipeline.
2. The method of claim 1 wherein a plurality of the components within the data analytics pipeline read input data from and write output data to shared storage that is accessible by each of the plurality of components.
3. The method of claim 2 wherein the shared storage is included in one or more storage systems, and wherein the containers are executed in a container cluster that is external to the storage system.
4. The method of claim 3 wherein each of the one or more storage systems include a plurality of blades in a single chassis.
5. The method of claim 2 further comprising:
sending, from a first component to a second component, a pointer indicating a location within shared storage where the first component has stored its output; and
retrieving, by the second component, the output of the first component from the location within shared storage identified by the pointer.
6. The method of claim 5 wherein the pointer references a location in a storage system that is external to a container cluster that is executing a first container that includes the first component and a second container that includes the second component.
7. The method of claim 1 wherein only a single instance of each component exists.
8. An apparatus comprising a computer processor, a computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the steps of:
creating a data analytics pipeline having a component that is deployed within a container, wherein the container executes in a container cluster that is external to shared storage accessible by components of the data analytics pipeline;
creating a failover container, wherein the failover container is configured to support at least one of components of the data analytics pipeline;
responsive to detecting that a component within the data analytics pipeline has failed, deploying the component that has failed in the failover container;
removing the failed component from the data analytics pipeline; and
adding the component contained in the failover container to the data analytics pipeline.
9. The apparatus of claim 8 wherein a plurality of the components within the data analytics pipeline read input data from and write output data to shared storage that is accessible by each of the plurality of components.
10. The apparatus of claim 9 wherein the shared storage is included in one or more storage systems, and wherein the containers are executed in a container cluster that is external to the storage system.
11. The apparatus of claim 10 wherein each of the one or more storage systems include a plurality of blades in a single chassis.
12. The apparatus of claim 9 further comprising computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the step of:
sending, from a first component to a second component, a pointer indicating a location within shared storage where the first component has stored its output; and
retrieving, by the second component, the output of the first component from the location within shared storage identified by the pointer.
13. The apparatus of claim 12 wherein the pointer references a location in a storage system that is external to a container cluster that is executing a first container that includes the first component and a second container that includes the second component.
14. The apparatus of claim 8 wherein only a single instance of each component exists.
15. A computer program product disposed on a non-transitory computer readable medium, the computer program product including computer program instructions that, when executed, carry out the steps of:
creating a data analytics pipeline having a component that is deployed within a container, wherein the container executes in a container cluster that is external to shared storage accessible by components of the data analytics pipeline;
creating a failover container, wherein the failover container is configured to support at least one of components of the data analytics pipeline;
responsive to detecting that a component within the data analytics pipeline has failed, deploying the component that has failed in the failover container;
removing the failed component from the data analytics pipeline; and
adding the component contained in the failover container to the data analytics pipeline.
16. The computer program product of claim 15 wherein a plurality of the components within the data analytics pipeline read input data from and write output data to shared storage that is accessible by each of the plurality of components.
17. The computer program product of claim 16 wherein the shared storage is included in one or more storage systems, and wherein the containers are executed in a container cluster that is external to the storage system.
18. The computer program product of claim 17 wherein each of the one or more storage systems include a plurality of blades in a single chassis.
19. The computer program product of claim 16 further comprising computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the step of:
sending, from a first component to a second component, a pointer indicating a location within shared storage where the first component has stored its output; and
retrieving, by the second component, the output of the first component from the location within shared storage identified by the pointer.
20. The computer program product of claim 19 wherein the pointer references a location in a storage system that is external to a container cluster that is executing a first container that includes the first component and a second container that includes the second component.
