Hi dev,
another easy refactoring is to merge the modules jdbm-store and
jdbm-partiton.
+1. Which one will you keep ? jdbm-store ?
To me, a partition is associated with a naming context, not with an
underlying store. That implies we should get rid of those XXX-partition
to just keep xxx-store, and keep the partitions at a upper layer (ie, core)
I wanted to keep the jdbm-partition module.
To me the partition is the concept that the core knows. The core knows
nothing about stores. We also define partitions in the configuration,
not stores.
This is how I understand the architecture:
1. The core defines the Partition interface
+1
2. XDBM provides an abstract implemementation of the Partition interface
and additionally defines the Store interface and search engine.
+1
3. The JDBM partition is a concrete implementation of the XDBM
partition. It contains a Store implementation because this is forced by
XDBM.
Here, I disagree. JDBM is a store, not a partition. XDBM = XXX-Data
Base Manager, nothing connected to the idea of Partition.
We could probably say that XDBM and Store is the same concept.
But let's discuss this aspect further, I may perfectly be wrong, I'm
just trying to manipulate concepts here.
