Abstract

In an example embodiment, a new solution is provided for an in-memory database provided in a cloud as a service that enables “job cross running” instead of “parallel job running.” Specifically, job scripts are clustered based on a shared service. A primary job script in the cluster is compiled and executed, but secondary job scripts in the cluster are not compiled until after the execution of the primary job script has begun. A mock library is inserted into each of the secondary job scripts to cause service calls for the shared service in the secondary job scripts to be replaced with mock service calls. The secondary job scripts are then scheduled and executed, and upon completion the primary job script is permitted to delete the shared service.

Claims20

Dependent claims

A system comprising:

at least one hardware processor;
and
a computer-readable medium storing instructions that, when executed by the at least one hardware processor, cause the at least one hardware processor to perform operations comprising:
clustering a plurality of job scripts together based on each of the plurality of job scripts invoking a particular service, each job script including a plurality of instructions to be executed by a computer to execute a job;
identifying a primary job script in the plurality of job scripts, with all other job scripts in the plurality of job scripts being secondary job scripts;
compiling the primary job script;
inserting a mock library into each of the secondary job scripts, the mock library including script commands that, when compiled, modify any service creation calls for the particular service in the corresponding secondary job script into mock service creation calls and modify any service deletion calls for the particular service in the corresponding secondary job into mock service deletion calls;
executing the compiled primary job script;
compiling the secondary job scripts after execution of the compiled primary job script has been initiated;
and
scheduling the secondary job scripts.

A method comprising:

clustering a plurality of job scripts together based on each of the plurality of job scripts invoking a particular service, each job script including a plurality of instructions to be executed by a computer to execute a job;
identifying a primary job script in the plurality of job scripts, with all other job scripts in the plurality of job scripts being secondary job scripts;
compiling the primary job script;
inserting a mock library into each of the secondary job scripts, the mock library including script commands that, when compiled, modify any service creation calls for the particular service in the corresponding secondary job script into mock service creation calls and modify any service deletion calls for the particular service in the corresponding secondary job into mock service deletion calls;
executing the compiled primary job script;
compiling the secondary job scripts after execution of the compiled primary job script has been initiated;
and
scheduling the secondary job scripts.

5 more elements

A non-transitory machine-readable medium storing instructions which, when executed by one or more processors, cause the one or more processors to perform operations comprising:

clustering a plurality of job scripts together based on each of the plurality of job scripts invoking a particular service, each job script including a plurality of instructions to be executed by a computer to execute a job;
identifying a primary job script in the plurality of job scripts, with all other job scripts in the plurality of job scripts being secondary job scripts;
compiling the primary job script;
inserting a mock library into each of the secondary job scripts, the mock library including script commands that, when compiled, modify any service creation calls for the particular service in the corresponding secondary job script into mock service creation calls and modify any service deletion calls for the particular service in the corresponding secondary job into mock service deletion calls;
executing the compiled primary job script;
compiling the secondary job scripts after execution of the compiled primary job script has been initiated;
and
scheduling the secondary job scripts.
