We are evaluating features of the Community edition of PostgreSQL in relation to a proposal for a prospective client and need help with the queries below:-
- Does the Community edition of PostgreSQL provide NATIVE active-active high availability clustering with objectives of scalability, load balancing and high availability without using any extensions or external components or usage of Kubernetes/Dockers.
Basically, no. See "logical replication" if you'd like to delve into why I qualified this one.
- In the Community edition of PostgreSQL is it possible to setup a database cluster in load balancing mode and provide vertical and horizontal scalability without repartitioning or changes to the database objects or 3rd party transaction routing mechanisms using NATIVE features only (i.e. without using any extensions or external components or usage of Kubernetes/Dockers).
No
- In the Community edition of PostgreSQL is it possible to setup a cluster where all the nodes are able to concurrently read-write the underlying database image using NATIVE features (i.e. without using any extensions or external components or usage of Kubernetes/Dockers).
No
There is only one server process per underlying data directory in PostgreSQL.
