Please estimate effort to implement Activiti 6.0 persistence in NoSQL database

[vtsurkan]

I am wondering what would be your best guesstimate at the effort in man hours.
I am not looking for any kind of precision, just generally want to know if it may or may not make sense to undertake the POC in that direction.

It's difficult to do an estimation myself as I am not that familiar with the new persistence interfaces in 6.0, so looking for someone who was involved in the design and implementation to just make a guess. If you can come up with some pros and cons of particular implementation - it would be fantastic.

Any kind of NoSQL (Cassandra, Mongo, etc) and Redis or Riak implementation would be of interest.

When making a guesstimate I think it's reasonable to assume good working proficiency with Java and Activiti 5.xx

Thanks

It depends a lot on how easy it is to 'mimic' the transactionality / compensation.
For Mongo for example, I'd say it would be at least 2-3 months to get to a decent state… but that's assuming all goes smooth and no hidden pitfalls are discovered (which there will certainly be).

But I'm a really bad estimator 😉
