<tt>Hey All,<br>
<br>
Now that 3.7 is out, here are some thoughts on how we can shape up
3.8. I am thinking of releasing Gluster 3.8 towards the end of
this year. Here is a tentative list of things that we are
contemplating to do in 3.8:<br>
<br>
1. Improvements for "Storage as a Service"<br>
<br>
"Storage as a Service" broadly refers to the model where
storage can be provisioned or decommissioned on demand, storage
caters to single or multi tenant workloads and completely
automated provisoning of storage is possible. Storage as a Service
is what public/private clouds use as a building block today. By
selecting enhancements and improvements that fit into this
paradigm, we can make Gluster to be more easily adopted in modern
datacenters. Following are sample use cases/workloads that can
benefit by gluster improvements:<br>
<br>
- Manila: File Share as a service project in OpenStack<br>
- Shared Storage for Containers<br>
- Any deployment where shares are created as a service <br>
<br>
<br>
Enhancements that can be accomplished in this release include:<br>
<br>
a. Intelligent Volume provisioning through Heketi [1]<br>
b. Kerberized support for GlusterFS protocol<br>
c. Better network management support [2]<br>
<br>
<br>
2. Regression test & Quality improvements<br>
<br>
We have zeroed in on distaf[3] as the framework of choice where we
will be adding support for multi-node regression tests. This will
augment the single node pre-commit regression tests that we
already run today with Jenkins. I expect tests in distaf passing
as a gating factor for GA of all releases from 3.8. Here is what
we would like to do in this release cycle:<br>
<br>
a. all gluster components to have tests populated in distaf<br>
b. CI using Jenkins for running tests in distaf on
nightlies/release candidates<br>
<br>
<br>
3. Storage for Containers<br>
<br>
There seems to be significant attention on storage for containers
recently. We can cater to this interest by picking specific
improvements for container storage like:<br>
<br>
a. shared storage for applications in containers (already possible
with nfs today). Explore how we can do this with native client etc.<br>
b. shared storage for docker/container repositories<br>
c. hyperconvergence of containers & storage<br>
<br>
4. Hyperconvergence with oVirt<br>
<br>
There is an ongoing effort to have hyperconvergence of gluster
with oVirt for storing virtual machine images in a single cluster
[4]. Improvements like the following can help in making Gluster a
better fit for hyperconvergence:<br>
<br>
a. Throttling for maintenance operations in gluster
(self-healing/rebalance etc.)<br>
b. Ensuring data locality for virtual machine images<br>
c. Integration of sharding for hyperconvergence (expect to reach
here sooner than 3.8)<br>
<br>
5. Performance improvements<br>
<br>
a. Continue the onoging small file performance improvements [5]<br>
b. multi-threaded self-heal daemon for improving performance of
self-healing<br>
<br>
6. Other improvements like full fledged IPv6 support,
delegations/lease-lock improvements, more policies for tiering, support
for systematic erasure codes, support for native object service
etc. are also planned.</tt><br>
<br>
<tt>There are other improvements which are being planned and have
not found a mention here. If you are aware of such improvements,
please reply to this thread. I will be collating this information
and publish a release planning page for 3.8 in gluster.org.</tt><br>
<br>
<tt>If you have come all the way till here, we would be interested
in knowing the following:<br>
<br>
(i) What are your thoughts on the plan?<br>
(ii) What other improvements would you be interested in seeing?<br>
<br>
Thoughts and feedback would be very welcome!<br>
<br>
Thanks,<br>
Vijay<br>
