Writing composite objects to a data store

A system, comprising:

• a processor;
• and
• a memory storing instructions which, when executed on the processor, perform an operation for writing data to a data store, the operation comprising:
• receiving, from a client device, a write request specifying an object to be written to the data store;
• determining, based on traversing an object dependency graph defining the specified object and identifying relationships between the specified object and dependency objects of the specified object, dependency objects to be written to a plurality of data stores including the data store, wherein the dependency objects comprise objects stored across the plurality of data stores or objects to be written across the plurality of data stores prior to writing the specified object to the data store;
• generating a plurality of write requests for the specified object and the dependency objects, each of the plurality of write requests being directed to one of the plurality of data stores;
• generating an execution plan for the plurality of write requests based on the object dependency graph;
• and
• executing the plurality of write requests against the plurality of data stores based on the execution plan.

A non-transitory computer-readable medium comprising instructions which, when executed on one or more processors, performs an operation for writing data to a data store, the operation comprising:

• receiving, from a client device, a write request specifying an object to be written to the data store;
• determining, based on traversing an object dependency graph defining the specified object and identifying relationships between the specified object and dependency objects of the specified object, dependency objects to be written to a plurality of data stores including the data store, wherein the dependency objects comprise objects stored across the plurality of data stores or objects to be written across the plurality of data stores prior to writing the specified object to the data store;
• generating a plurality of write requests for the specified object and the dependency objects, each of the plurality of write requests being directed to one of the plurality of data stores;
• generating an execution plan for the plurality of write requests based on the object dependency graph;
• and
• executing the plurality of write requests against the plurality of data stores based on the execution plan.
