+1 for&nbsp; 0.14.0-preview, and propose v0.13.1 and v0.12.6 at the same time.

&gt;
&gt; I even want to use -beta previously :D
&gt;

&gt; &gt; Good news! How about '0.14.0-preview' ? As in general development we
&gt; &gt; always use *-alpha as an internal test version with all main features
&gt; &gt; present. As the description of the version, it mainly contains the new
&gt; &gt; cluster.

&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; Hi all,
&gt; &gt;
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; It has been 4~5 months since we started the 
new cluster version.
&gt; &gt; Thanks for
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; the contribution of all contributors!
&gt; &gt;
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; It's time to start the topic of releasing :)
&gt; &gt;
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; The summary status of the master branch is as 
follows:
&gt; &gt;
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; (1) The new cluster version has many 
advantages compared to the old
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; one(0.12~0.13).
&gt; &gt;
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; * MPP Query Engine, we use volcano module 
with operators for better
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; extendibility in data processing.
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; * Configurable consensus protocol 
(Standalone, Raft, Multi-Leader) for
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; Partition, Schema and Data.
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; * Controlable partition table, so that we 
could control which node to
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; manage data.
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; * No whole cluster consensus group.
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; * More flexible and lightweight scale-out, we 
could add a node in a few
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; seconds without moving&nbsp; data.
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; * Extensible load balance strategy.
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; * Built-in metric framework to monitor the 
status of the cluster.
&gt; &gt;
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; (2) We have implement the basic function 
(read/write/schema/udf) of
&gt; &gt; the new
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; Cluster/standalone version.
&gt; &gt;
&gt; &gt;

&gt; &gt;
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; There are still some functions that need to 
be implemented in new
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; Cluster/standalone.
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; * Trigger
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; * Schema Template
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; * Continuous Query
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; * Select into
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; * Sync framework
&gt; &gt;
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; (3) The performance&nbsp; optimization of the 
new Cluster is still going.
&gt; &gt;

&gt; &gt;
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; * Write performance of one replication with 
standalone/multiLeader in
&gt; &gt; new
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; cluster. [ok].
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; * Write performance of one replication with 
Ratis. [underway]
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; * Write performance of three replication with 
Ratis/MultiLeader.
&gt; &gt; [underway]
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; * Query performance of one replication with
&gt; &gt; standalone/ratis/multileader.
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; [underway]
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; * Query performance of three replication with 
Ratis/MultiLeader.
&gt; &gt; [underway]
&gt; &gt;
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; I suppose we could get a not-bad number by 
this weekend for all above
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; scenaios.
&gt; &gt;
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; (4) More test needs to be done to improve the 
stability of the new
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; cluster/standalone, and the ITs are being 
added.
&gt; &gt;
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; As this version does not contains the whole 
functions of 0.13, and the
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; system performance and stability need to be 
improved for some time
&gt; &gt; before
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; produnction, I suggest retaining the 0.14.0 
version number.
&gt; &gt;
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; So, how about using 【0.14.0-alpha】, and we 
only release the binary
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; distribution of new cluster, without new/old 
standalone version.
&gt; &gt;
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; Then, for the formal 0.14.0, we could release 
the new
&gt; &gt; Cluster/Standalone
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; version and discard the old Standalone 
version.
&gt; &gt;
&gt; &gt;&nbsp;&nbsp;&nbsp;&nbsp; Thanks,
