Multi-tier storage system having a front-end storage tier facilitating efficient graph analytics computations

A method comprising:

• configuring a multi-tier storage system for communication over at least one network with a plurality of compute nodes, the multi-tier storage system comprising at least a front-end storage tier and a back-end storage tier;
• implementing at least one dispatcher node configured to load portions of graph data from the front-end storage tier and the back-end storage tier for graph analytics computations performed at respective ones of a plurality of compute nodes configured for communication with the storage system over at least one network;
• and
• switching logical connections of respective ones of the compute nodes to the at least one dispatcher node based on progress of graph analytics computations at the compute nodes;
• wherein the method is performed using at least one processing device comprising a processor coupled to a memory.

A non-transitory processor-readable storage medium having stored therein program code of one or more software programs, wherein the program code when executed by at least one processing device causes said processing device:

• to configure a multi-tier storage system for communication over at least one network with a plurality of compute nodes, the multi-tier storage system comprising at least a front-end storage tier and a back-end storage tier;
• to implement at least one dispatcher node configured to load portions of graph data from the front-end storage tier and the back-end storage tier for graph analytics computations performed at respective ones of a plurality of compute nodes configured for communication with the storage system over at least one network;
• and
• to switch logical connections of respective ones of the compute nodes to the at least one dispatcher node based on progress of graph analytics computations at the compute nodes.
