"Thank You for great video with usefull explanation. What will be the time costs for hot deploy of changed code in case when the application is classical monolithic application (like Java EE or Spring based one) ? Will be the application restarted completely or the changed code will be hot swapped only with this approach?" from: https://www.youtube.com/watch?v=_c8ZkSSpdWI&lc=UgxatJ9VbfxZFmiEpLN4AaABAg

How to JPA Multitenancy with JavaEE, Inject, CDI, Payara 5 (not plain hibernate, without spring data) ? Must be transactional out of the box without weird magic.

;)

  • single database server (mysql 8)
  • multiple schemas for tenants (n-schemas)
  • one schema per tenant (n-tables)
  • one schema for storing users, app settings etc (n-tables)..

Maybe some examples and guides or different approache. Thanks.

Interested to see what Adam has to say here, as well. As far as I'm aware - multitenancy is not included in the JPA spec but is supported by provider-specific extensions. You mention Payara - that indicates eclipselink - have you taken a look at the eclipselink solution guide?
