Processing distributed jobs using multiple connections

A system, comprising:

• a memory;
• and
• one or more processing devices coupled to the memory, the one or more processing devices to implement a first execution environment to:
• transmit, by a first component of the first execution environment via a first connection to a second component of a second execution environment, a first request associated with a job;
• receive, by the first component via a second connection from the second component, a pull synchronization request associated with the job;
• transmit, by the first component via the second connection to the second component, a response to the pull synchronization request, the response comprising data associated with the job;
• receive, by the first component via the first connection from the second component, a result of the job, wherein the result is based on the response to the pull synchronization request;
• and
• responsive to receiving the result, close the first connection and keeping the second connection open.

A non-transitory computer readable storage medium encoding instructions thereon, which in response to execution by one or more processing devices cause the one or more processing devices to implement a first execution environment to:

• transmit, by a first component of the first execution environment via a first connection to a second component of a second execution environment, a first request associated with a job;
• receiving, by the first component via a second connection from the second component, a pull synchronization request;
• transmit, by the first component via the second connection to the second component, a response to the pull synchronization request, the response comprising data associated with the job;
• receive, by the first component via the first connection from the second component, a result of the job, wherein the result is based on the response to the pull synchronization request;
• and
• responsive to receiving the result, close the first connection and keeping the second connection open.
