i have number of microservices maintain own databases (mongodb, elastic, mysql) , each of microservices have set-up new connection constantly. i considering wise if created microservice, handle these connections microservices, before start up. example: api gateway microservice gets request search, calls search microservice, before search starts, calls database setup miscroservice , returns established connection it, based on microservice called (in case - search microservice). would better, if found out connection needed inside api gateway? or should leave logic separately in each microservice. you break microservices encapsulation assuming type of persistence each microservice using. each microservice should free use whatever persistence type wants or change when wants transparently, without notifying or requesting permission other microservices this.

is there provision store user entered comment during modification “model” can shown in “audit view” along “original” , “change” columns of ea. can add comment column next change column in audit view of ea, user entered comment can stored. please suggest ea api same. you can not that. might modify underlying database , add columns existing tables (or add private tables). break xmi export these columns not ex-/imported , you're on own maintain this. alternative use tagged values in general cases. here doubt it's feasible. own table foreign key referring audit choice. however, merely sound you're trying re-build check-in mechanism. fwiw: in practice found mechanism counter-productive people tend comment either nothing or trivialities. hinders more helps. you can not modify standard dialogs (e.g. fo shown audit view). means have write add-in create own dialog. the table contains audit t_snapshot .
