Keith Wall commented on QPID-7873:
----------------------------------
There is a defect. I am using Maria DB.
# Add JSON VHN with JDBC VH
# Run a {{show tables}} - expected messaging tables have been created
# Delete the VHN
# Repeat {{show tables }} *defect* - AMQP_1_0_LINKS and AMQP_1_0_LINKS_VERSION
remain.
If I create a JDBC backed VHN with Provided Store, the same issue does not
appear.

> [Broker-J] Delete store notion confused
> ---------------------------------------
>
> Key: QPID-7873
> URL: https://issues.apache.org/jira/browse/QPID-7873
> Project: Qpid
> Issue Type: Improvement
> Components: Broker-J
> Reporter: Keith Wall
> Assignee: Alex Rudyy
> Priority: Major
> Fix For: Future
>
>
> org.apache.qpid.server.store.MessageStore#onDelete
> org.apache.qpid.server.store.DurableConfigurationStore#onDelete
> org.apache.qpid.server.protocol.v1_0.store.LinkStore#delete
> The Java Broker's delete store notion conflates the removal of the structures
> from the store (e.g. the removal of a table from a RDBMS, for instance) with
> the destruction of the store itself (e.g. removal of Derby or BDB files). We
> are also unclear about whether we expect a store to be in an open state when
> the store is deleted.
> This problem does not currently cause a functional defect.
