class DbLockedConnection extends NamedLogging with FlagCloseable with HasCloseContext with StateMachine[State]
Maintains the combination of a persistent DB connection and a DB lock acquired on that connection.
If the connection is closed or becomes invalid, it will try to rebuild the connection and re-acquire the lock.

Returns a connection only if the connection is available and the lock has been acquired.
The consumer should get a connection when needed and not cache the returned connection to ensure that the connection is healthy when used.

Use this method to create a PromiseUnlessShutdown that will automatically be cancelled when the close context is closed.
Use this method to create a PromiseUnlessShutdown that will automatically be cancelled when the close context is closed. This allows proper clean up of stray promises when the node is transitioning to a passive state.
Note: you should *not* invoke
success
on the returned promise but rather usetrySuccess
. The reason is that the call tosuccess
may fail in case of shutdown.- Definition Classes
