Generating an idempotent workflow

One or more computer-readable storage media to generate a workflow comprising a plurality of instructions that, when executed by a processor, cause the processor to:

• identify a boundary function that executes at least a first portion of distributed code on a first computing device and at least a second portion of the distributed code on a second computing device different from the first computing device;
• separate the boundary function into a plurality of sub-functions based, at least in part, on operating characteristics corresponding to each of the plurality of sub-functions, wherein a first sub-function of the plurality of sub-functions generated from the boundary function has a first operating characteristic and a second sub-function of the plurality of sub-functions generated from the boundary function has a second operating characteristic different from the first operating characteristic, wherein the plurality of sub-functions comprises a transition function that identifies a transition from the first computing device to the second computing device and a reversion function that terminates a session;
• transform the first sub-function of the plurality of sub-functions having the first operating characteristic to have the second operating characteristic different from the first operating characteristic to produce a single output value from multiple executions of the first sub-function of the plurality of sub-functions by storing a flag indicating whether the first sub-function of the plurality of sub-functions has been executed;
• and
• combine the plurality of sub-functions to form a workflow having the second operating characteristic based, at least in part, on the flag.

A system for generating a workflow, comprising:

• one or more storage devices to store executable code;
• and
• one or more processing devices to execute the executable code to:
• identify a boundary function that executes at least a first portion of distributed code on a first computing device and at least a second portion of the distributed code on a second computing device different from the first computing device;
• separate the boundary function into a plurality of sub-functions based, at least in part, on operating characteristics corresponding to each of the plurality of sub-functions, wherein a first sub-function of the plurality of sub-functions generated from the boundary function has a first operating characteristic and a second sub-function of the plurality of sub-functions generated from the boundary function has a second operating characteristic different from the first operating characteristic;
• transform the first sub-function of the plurality of sub-functions having the first operating characteristic to have the second operating characteristic different from the first operating characteristic to produce a single output value from multiple executions of the first sub-function of the plurality of sub-functions by storing a flag indicating whether the first sub-function of the plurality of sub-functions has been executed;
• include code in the first sub-function of the plurality of sub-functions to enable the first sub-function of the plurality of sub-functions to execute only once;
• and
• combine the plurality of sub-functions to form a workflow having the second operating characteristic based, at least in part, on the flag.
