design patterns - Observer or Pub/Sub for dashboard (Springboot) -


we have manufacturing plant , there single sql table regularly updated every resource's running job , status. want have clients subscribe changes (by dept) in web app. (we building new microservice architecture , other functions). dept supervisors want see "real-time" status of department's resources , jobs. total of 20-30 users

which pattern best: pub/sub or observable

publisher / subscriber each time status change publish message , subcriber update information ,you can filter out message based on department , decide whether update infor or not.

observable notify linked members only.

suggested way go pub/sub

any new addition or deletion of services easy.

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
