I think The HAF framework and its hive_fork_manager solve the described problems. The HAF ( hive application framework ) is a plugin for hived (hive node) and hive_fork_manager. A system that allows You and other developers to easily create SQL-based applications. The HAF ensures data consistency and drives the processing of blocks by the applications. Because SQL is the interface for the applications, HAF can be used with any language which supports SQL. The HAF is still under development, but it is worth becoming familiar with it now, since we want to release it soon
