Universal DAO plugin for SQL databases like PostgreSQL, MySQL, etc.

See original GitHub issue

Implement DAO to work with any SQL database, possibly using a framework like JOOQ.

Para is schemaless so we need to decide how objects are going to be mapped to DB columns. One way to do this is by having a JSON column holding a ParaObject, serialized in JSON + an id column.

Ideas are welcome.

We’ll definitely need a connection pooling mechanism on top of JDBC. I propose we try HikariCP. I’ve never used it before, but it looks solid.

I started working on this issue and I’m realizing that even Hibernate is overkill what what is needed here - the DAO class is only doing the most basic CRUD operations. I’m thinking this implementation can just simply use JDBC. To use the generic SQL DAO plugin you would need to specify some basic properties like URL, user name and password of the database, and then the JDBC driver class name (i.e. “com.mysql.jdbc.Driver”). Lastly, you’d need to include the jarfile with the JDBC driver in it in your classpath when running Para server. What do you think about this?
