Abstract

This disclosure describes techniques for enabling efficient and/or expeditious retrieval of data records stored across a clustered storage framework. An example system manages storage of data records in the storage clusters based on predefined placement rules. Frequently accessed data records are stored in a local high-performance store storage medium to reduce retrieval latency. The system determines which storage cluster to retrieve a requested data record from by selecting the cluster with the highest weight, as determined based on performance-related metrics like cluster utilization and geographic proximity.

First claim

What is claimed is:

1 . A method comprising:receiving, by a processor and from a first computing device, a first request to retrieve a first data record from a storage framework, the storage framework comprising a first storage cluster and a second storage cluster;receiving, by the processor, a first weight of the first storage cluster and a second weight of the second storage cluster, wherein the first weight represents a first likelihood and the second weight represents a second likelihood;determining, by the processor and based on the first likelihood, the second likelihood, and a range associated with a probability distribution, a likelihood threshold;determining, by the processor, first data representing that a first value determined based on the probability distribution exceeds the likelihood threshold;providing, by the processor and based on the first data, the first request to the first storage cluster;receiving, by the processor and based on providing the first request to the first storage cluster, the first data record from the first storage cluster; andproviding, by the processor and to the first computing device, the first data record.

2 . The method of claim 1 , wherein determining the first data comprises:determining the first value based on sampling the probability distribution.

3 . The method of claim 1 , further comprising:
determining, by the processor, a retrieval latency associated with routing the first request to the first storage cluster and receiving the first data record from the first storage cluster; and updating, by the processor, the first weight based on the retrieval latency.

4 . The method of claim 1 , further comprising:determining, by the processor, a capacity measure associated with the first storage cluster; andupdating, by the processor, the first weight based on the capacity measure.

5 . The method of claim 1 , further comprising:receiving, by the processor, a notification about unavailability of the first storage cluster; andbased on receiving the notification, updating, by the processor, the first weight.

6 . The method of claim 1 , further comprising:determining, by the processor, a network utilization of the first storage cluster; andupdating, by the processor, the first weight based on the network utilization.

7 . The method of claim 1 , wherein the first likelihood represents a predicted likelihood of future failure of the first storage cluster.

8 . A computing system, comprising:a processor; and
memory storing computer-executable instructions that, when executed by the processor, cause the computing system to perform operations comprising:
receiving, by a processor and from a first computing device, a first request to retrieve a first data record from a storage framework, the storage framework comprising a first storage cluster and a second storage cluster;
receiving, by the processor, a first weight of the first storage cluster and a second weight of the second storage cluster, wherein the first weight represents a first likelihood and the second weight represents a second likelihood;
determining, by the processor and based on the first likelihood, the second likelihood, and a range associated with a probability distribution, a likelihood threshold;
determining, by the processor, first data representing that a first value determined based on the probability distribution exceeds the likelihood threshold;
providing, by the processor and based on the first data, the first request to the first storage cluster;
receiving, by the processor and based on providing the first request to the first storage cluster, the first data record from the first storage cluster; and
providing, by the processor and to the first computing device, the first data record.

9 . The computing system of claim 8 , wherein determining the first data comprises:determining the first value based on sampling the probability distribution.

10 . The computing system of claim 8 , the operations further comprising:determining, by the processor, a retrieval latency associated with routing the first request to the first storage cluster and receiving the first data record from the first storage cluster; and
updating, by the processor, the first weight based on the retrieval latency.

11 . The computing system of claim 8 , the operations further comprising:determining, by the processor, a capacity measure associated with the first storage cluster; andupdating, by the processor, the first weight based on the capacity measure.

12 . The computing system of claim 8 , the operations further comprising:receiving, by the processor, a notification about unavailability of the first storage cluster; andbased on receiving the notification, updating, by the processor, the first weight.

13 . The computing system of claim 8 , the operations further comprising:determining, by the processor, a network utilization of the first storage cluster; andupdating, by the processor, the first weight based on the network utilization.

14 . The computing system of claim 8 , wherein the first likelihood represents a predicted likelihood of future failure of the first storage cluster.

15 . One or more non-transitory computer-readable media storing computer-executable instructions that, when executed by a processor, cause the processor to perform operations, comprising:receiving, by a processor and from a first computing device, a first request to retrieve a first data record from a storage framework, the storage framework comprising a first storage cluster and a second storage cluster;
receiving, by the processor, a first weight of the first storage cluster and a second weight of the second storage cluster, wherein the first weight represents a first likelihood and the second weight represents a second likelihood; determining, by the processor and based on the first likelihood, the second likelihood, and a range associated with a probability distribution, a likelihood threshold; determining, by the processor, first data representing that a first value determined based on the probability distribution exceeds the likelihood threshold; providing, by the processor and based on the first data, the first request to the first storage cluster; receiving, by the processor and based on providing the first request to the first storage cluster, the first data record from the first storage cluster; and providing, by the processor and to the first computing device, the first data record.

16 . The one or more non-transitory computer-readable media of claim 15 , wherein determining the first data comprises:determining the first value based on sampling the probability distribution.

17 . The one or more non-transitory computer-readable media of claim 15 , the operations further comprising:determining, by the processor, a retrieval latency associated with routing the first request to the first storage cluster and receiving the first data record from the first storage cluster; andupdating, by the processor, the first weight based on the retrieval latency.

18 . The one or more non-transitory computer-readable media of claim 15 , the operations further comprising:determining, by the processor, a capacity measure associated with the first storage cluster; andupdating, by the processor, the first weight based on the capacity measure.

19 . The one or more non-transitory computer-readable media of claim 15 , the operations further comprising:receiving, by the processor, a notification about unavailability of the first storage cluster; andbased
