J=C3=B8rgen L=C3=B8land updated DERBY-2872:
---------------------------------

    Attachment: proof-of-concept_v2b-howto.txt
                poc_slave_v2b.diff
                poc_master_v2b.diff

*** Want to take the new Derby Asynchronous Replication Feature for a spin?=
 ***

The newly attached proof of concept code, poc_{master|slave}_v2b.diff can n=
ow be tested by anyone interested. Read the attached howto for instructions=
. Note: we are far from done with this,  but the current poc seems to work.=
 Good luck :)

> It would be nice to have replication functionality to Derby; many potenti=
al Derby users seem to want this. The attached functional specification lis=
ts some initial thoughts for how this feature may work.
> Dag Wanvik had a look at this functionality some months ago. He wrote a p=
roof of concept patch that enables replication by copying (using file syste=
m copy) and redoing the existing Derby transaction log to the slave (unfort=
unately, I can not find the mail thread now).
> DERBY-2852 contains a patch that enables replication by sending dedicated=
 logical log records to the slave through a network connection and redoing =
these.
> Replication has been requested and discussed previously in multiple threa=
ds, including these:
