multi tenant - Hazelcast data isolation ("Memory Regions") -


we building multi tenant application has restrictions on regions/countries data persisted.

the application based on microsoft .net microservice architecture have shared domains, although have separate dbs @ lower levels each city separate db. cannot persist data of 1 country in country's data center. hazelcast used distributed cache. not find direct ways configure data isolation ex. "memory regions" in apache ignite. have "memory regions" in hazelcast?

i need write behind data cache respective database. can segregate part/partition of cache specific database instance?

any appreciated. in advance.

i not directly replying question. imho, understanding when have data stored across different clusters / nodes, there still network call, despite having key formats data stored within same cluster / node.

based on experience, setup memorycache comes part of system.runtime.caching store data in every node , use redis pub-sub or azure service bus back-bone pub-sub.

in case,

  • any data updated in cache notified other instances of application via servicebus / redis message typically key.

  • upon receipt of key, each application clears out internal cache , gets data cached on next db access.

this method more commonly prevalent in multi-tenant applications , fail-safe , light weight. payloads / network transfers less , each appdomain has internal memory used cache support different regions via different instances of memorycache.

hope helps if no direct response available regarding hazelcast

also, may refer link details regarding hazelcast

Add a dynamic header in angular 2 http provider -

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
