database - All my microservices have their own db's, should I create common microservice to handle connections? -


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.

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
