Emakin performs most of heavy operations in background to archive scalable and high performance output. These background operations are executed by emakin service agent without any user interaction.

When a new process started by user, workflow state is recorded in database without any further processing and creates couple of background jobs. Service agents pulls the jobs from queue and try to process in background. If a error occurred while processing job, transaction state is roll backed and error state is reported to the system administrators. When administrator resolves the issue, job re-queued in system from job manager to process again. Some of errors are automatically recovered by system and queued again with time delay.

Service agents uses multiple threads and also can be deployed to any number of hardware instances to perform parallel execution. Jobs are executed in order of priority and a single service agent can complete 600 job per minute for basic workflow operations. This number is highly depends on job definition and hardware specifications.
