Subject Re: Community Process for 0.20.205 Sustaining Release
Date Wed, 24 Aug 2011 16:32:26 GMT
Hi Milind,

I'm really happy to see 0.23 moving along.  This seems like pretty clear evidence that 0.20.xxx
is not going to be a new trunk.  However, the time between cutting a new release and being
able to run production applications on it can be very long.  0.23 and any alternative such
as 0.22 will take a long time to get to the level of quality and stability that is in 0.20.xxx
today.  Trunk is looking very healthy to me.  Having a good sustaining program on 0.20.xxx
is intended to compliment mainline dev, not replace it.  Describing fixing flush/sync as innovation
seems like a stretch.  The patch sets we are considering merging have been in use for more
than a year.

There is a large constituency that would like to see HBASE work well now.  I'm hoping to see
that happen on 0.20.xxx.  I think this is the best place to invest effort.  You are welcome
to work with the community members investing in 0.20.xxx or on an alternative.  There is room
in the community for both efforts IMO.
