Reorder database mappings to improve loading times

See original GitHub issue

Acceptance Criteria (Required on creation)

The database mappings are ordered in a way that BuilderExceptions don’t occur

Hints

BuilderExceptions occur when loading MyBatis mappings and cross-referenced scripts are not yet loaded.
The failed mappings are retried later on again. This increases the loading time of all mappings overall.

Links

n/a

Breakdown

Identify the references due to which script loading is failing
Reorder the mappings to load to get rid of the loading failures

Hi @tobiasschaefer,

good point regarding edits/updates, I wasn’t aware actually, and will keep that in mind in the future 👍

Regarding time reductions:

Module	Old time (sec)	New time (sec)	Improvement
Overall	1740	1500	~14%
Engine Core	300	220	~27%
Engine Spring	150	90	~40%
Spring Boot Starter Core	53	38	~28%
Spring Boot Starter Webapps	43	32	~26%
Camunda Run Core	60	40	~33%

Hope that helps 🙂

Hi @tmetzke ,

thanks a lot for those numbers (unfortunately I first missed the updates 1 and 2 because edits of existing comments don’t seem to trigger notifications).

Those numbers are quite impressive - especially when extrapolated to all camunda7 installations world wide. Test suites of Spring Boot applications which use @DirtiesContext will profit a lot 🙂

Regarding “update 2”. What was the initial time so that I can assess how much those 4 minutes are worth?

And how much faster (absolute and relative values) are the Spring and Spring-Boot related modules?

I’d love to hear some numbers. Even if the changes look trivial it took me quite some time to narrow down the issue.
