Routing for data grid in a computing cluster

A system comprising:

• a memory;
• a processing device coupled to the memory, the processing device to perform operations comprising:
• computing a partition number by using a consistent hash function based on a key of an entry, wherein the entry is stored or to be stored in an owner node;
• adding the partition number to a request to access the owner node;
• sending the request to a routing system, wherein the routing system identifies the owner node based on the partition number in the request, wherein the routing system is created in view of a data grid topology of a containerized computing cluster, wherein the containerized computing cluster comprises a plurality of nodes, wherein the plurality of nodes are divided into a plurality of partitions and each partition of the plurality of partitions is identified by a respective partition number, and wherein the data grid topology maps the respective partition number to an address of corresponding nodes for the respective partition;
• and
• receiving, from the owner node, a response to the request.

A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:

• receiving a description of a data grid topology of a containerized computing cluster, wherein the containerized computing cluster comprises a plurality of nodes, wherein the plurality of nodes are divided into a plurality of partitions and each partition of the plurality of partitions is identified by a respective partition number, and wherein the data grid topology maps the respective partition number to an address of corresponding nodes for the respective partition;
• and
• in view of the data grid topology, creating a routing system, wherein the routing system is configured to route a request to an owner node, wherein the request specifies the owner node by using a particular partition number, wherein creating the routing system comprises:
• labeling each pod with a partition number according to the data gird topology, wherein each pod comprises one or more virtualized computing entities running on one or more host computer systems, wherein each pod corresponds to a node of the plurality of nodes;
• creating a service for each partition number, wherein the service comprises an application programmer interface (API) object identifying at least one pod;
• and
• creating a routing API object to route the request to the service.
