Hi all, We have a requirement of writing a multiple Nested Cdt's and Webservice Records into different tables in MySQL Database. I successfully started to push couple of CDT's with multiWrite DataStore smart service. I want push all Values at one time. Is there any best practice to be followed while doing this? I read, keep the data <1MB as one of the best practice. Is there anyway to measure data transfer??

Hi Ramasehur... Multiple nested CDTs and nesting CDTs is NOT an Appian best practice - I would avoid nesting and keep a flatter structure when possible.

However a flatter structure is often not good database design... When correct normalisation is required due to integrations or whatever, we have sometimes reverted to calling stored procs passing in parameter values which again isn't something that's always recommended but sometimes needs must. :-/

Hi Chrism... Yeah, I get it. I always proceed with caution if I intentionally break an Appian Best Practice.... but I understand... I would def document this and also do some extra performance testing for end-user experience!

Thank Danny and Chrism,
chrism, We were using Stored Procs in my old project. In this project we cannot pull that kind of resource now. Currently, we have been using multiple External Databases and web service calls for Data Flow until now.Trying to build a Data Store from scratch and i want to follow Best Practices.

Is there a way to measure the Data transfer ??
Our application has lot of Web CDT's and multiple nested CDT's to push into our Data Store.
