Re: [GUSDEV] Support for workflows ?

[Angel P. <an...@ma...>]

Agreement with Mike here. GUS used to have a set of tables to capture 
the state of workflows, such as a build of the dna assemblies. These 
tables where agonized over and well thought out, but ultimately went 
unused and have subsequently been deleted from the schema. There are 
several reasons:

-Most of the tasks we faced in a workflow where serial and did not 
contain any sort of decision points.
-Using flat files to record state and recover from errors works just 
fine and is much easier to implement when the above holds true.

Additionally, there are many workflow-focused open source projects out 
there that you can use to define and record the state of complex asynch 
workflows that are much more well thought out and are actually supported 
by an enthusiastic community. I recommend that if you want to pursue 
this further, you take advantage of work being done in the workflow 
management systems space, and limit the use of GUS to a data model that 
a particular workflow accesses.
