<!-- Documentation -->
<p class="post-meta"></p>
<div class="documentation-content"><h2 id="roles-and-responsibilities">Roles and Responsibilities</h2>
<p>Apache projects define a set of roles with associated rights and responsibilities. These roles govern
what tasks an individual may perform within the project. The roles are defined in the following
sections:</p>
<h3 id="users">Users:</h3>
<p>The most important participants in the project are people who use our software. The majority of our
developers start out as users and guide their development efforts from the user&#39;s
perspective.</p>
<p>Users contribute to the Apache projects by providing feedback to developers in the form of bug
reports and feature suggestions. As well, users participate in the Apache community by helping other
users on mailing lists and user support forums.</p>
<h3 id="contributors">Contributors:</h3>
<p>Contributors are all of the volunteers who are contributing time, code, documentation, or resources
to the Storm Project. A contributor that makes sustained, welcome contributions to the project may
be invited to become a Committer, though the exact timing of such invitations depends on many
factors.</p>
<h3 id="committers">Committers:</h3>
<p>The project&#39;s Committers are responsible for the project&#39;s technical management. Committers
have access to all project source repositories. Committers may cast binding votes on any technical
discussion regarding storm.</p>
<p>Committer access is by invitation only and must be approved by lazy consensus of the active PMC
members. A Committer is considered emeritus by their own declaration or by not contributing in any
form to the project for over six months. An emeritus Committer may request reinstatement of commit
access from the PMC. Such reinstatement is subject to lazy consensus approval of active PMC
members.</p>
<p>All Apache Committers are required to have a signed Contributor License Agreement (CLA) on file with
the Apache Software Foundation. There is a <a href="https://www.apache.org/dev/committers.html">Committers&#39;
FAQ</a> which provides more details on the requirements for Committers.</p>
<p>A Committer who makes a sustained contribution to the project may be invited to become a member of
the PMC. The form of contribution is not limited to code. It can also include code review, helping
out users on the mailing lists, documentation, testing, etc.</p>
<h3 id="project-management-committee-pmc">Project Management Committee(PMC):</h3>
<p>The PMC is responsible to the board and the ASF for the management and oversight of the Apache Storm
codebase. The responsibilities of the PMC include:</p>
<ul>
<li>Deciding what is distributed as products of the Apache Storm project. In particular all releases
must be approved by the PMC.
</li>
<li>Maintaining the project&#39;s shared resources, including the codebase repository, mailing
lists, websites.
</li>
<li>Speaking on behalf of the project.</li>
<li>Resolving license disputes regarding products of the project.</li>
<li>Nominating new PMC members and Committers.</li>
<li>Maintaining these bylaws and other guidelines of the project.</li>
</ul>
<p>Membership of the PMC is by invitation only and must be approved by a consensus approval of active
PMC members. A PMC member is considered &quot;emeritus&quot; by their own declaration or by not
contributing in any form to the project for over six months. An emeritus member may request
reinstatement to the PMC. Such reinstatement is subject to consensus approval of the active PMC
members.</p>
<p>The chair of the PMC is appointed by the ASF board. The chair is an office holder of the Apache
Software Foundation (Vice President, Apache Storm) and has primary responsibility to the board for
the management of the projects within the scope of the Storm PMC. The chair reports to the board
quarterly on developments within the Storm project.</p>
<p>The chair of the PMC is rotated annually. When the chair is rotated or if the current chair of the
PMC resigns, the PMC votes to recommend a new chair using Single Transferable Vote (STV) voting. See
<a href="http://wiki.apache.org/general/BoardVoting">http://wiki.apache.org/general/BoardVoting</a>
for specifics. The decision must be ratified by the Apache board.</p>
<h2 id="voting">Voting</h2>
<p>Decisions regarding the project are made by votes on the primary project development mailing list (<a
href="mailto:dev@storm.apache.org">dev@storm.apache.org</a>). Where necessary, PMC voting may
take place on the private Storm PMC mailing list. Votes are clearly indicated by subject line
starting with [VOTE]. Votes may contain multiple items for approval and these should be clearly
separated. Voting is carried out by replying to the vote mail. Voting may take four flavors:</p>
<table>
<thead>
<tr>
<th>Vote</th>
<th>Meaning</th>
</tr>
</thead>
<tbody>
<tr>
<td>+1</td>
<td>&#39;Yes,&#39; &#39;Agree,&#39; or &#39;the action should be performed.&#39;</td>
</tr>
<tr>
<td>+0</td>
<td>Neutral about the proposed action.</td>
</tr>
<tr>
<td>-0</td>
<td>Mildly negative, but not enough so to want to block it.</td>
</tr>
<tr>
<td>-1</td>
<td>This is a negative vote. On issues where consensus is required, this vote counts as a veto.
All vetoes must contain an explanation of why the veto is appropriate. Vetoes with no
explanation are void. It may also be appropriate for a -1 vote to include an alternative
course of action.
</td>
</tr>
</tbody>
</table>
<p>All participants in the Storm project are encouraged to show their agreement with or against a
particular action by voting. For technical decisions, only the votes of active Committers are
binding. Non-binding votes are still useful for those with binding votes to understand the
perception of an action in the wider Storm community. For PMC decisions, only the votes of active
PMC members are binding.</p>
<p>Voting can also be applied to changes already made to the Storm codebase. These typically take the
form of a veto (-1) in reply to the commit message sent when the commit is made. Note that this
should be a rare occurrence. All efforts should be made to discuss issues when they are still
patches before the code is committed.</p>
<p>Only active (i.e. non-emeritus) Committers and PMC members have binding votes.</p>
<h2 id="approvals">Approvals</h2>
<p>These are the types of approvals that can be sought. Different actions require different types of
approvals</p>
<table>
<thead>
<tr>
<th>Approval Type</th>
<th>Criteria</th>
</tr>
</thead>
<tbody>
<tr>
<td>Consensus Approval</td>
<td>Consensus approval requires 3 binding +1 votes and no binding vetoes.</td>
</tr>
<tr>
<td>Majority Approval</td>
<td>Majority approval requires at least 3 binding +1 votes and more +1 votes than -1 votes.</td>
</tr>
<tr>
<td>Lazy Consensus</td>
<td>Lazy consensus requires no -1 votes (&#39;silence gives assent&#39;).</td>
</tr>
<tr>
<td>2/3 Majority</td>
<td>2/3 majority votes requires at least 3 votes and twice as many +1 votes as -1 votes.</td>
</tr>
</tbody>
</table>
<h3 id="vetoes">Vetoes</h3>
<p>A valid, binding veto cannot be overruled. If a veto is cast, it must be accompanied by a valid
reason explaining the reasons for the veto. The validity of a veto, if challenged, can be confirmed
by anyone who has a binding vote. This does not necessarily signify agreement with the veto - merely
that the veto is valid.</p>
<p>If you disagree with a valid veto, you must lobby the person casting the veto to withdraw their veto.
If a veto is not withdrawn, any action that has been vetoed must be reversed in a timely manner.</p>
<h2 id="actions">Actions</h2>
<p>This section describes the various actions which are undertaken within the project, the corresponding
approval required for that action and those who have binding votes over the action.</p>

after the patch was posted, it may be reverted immediately if it was already merged.

<h5>About Apache Storm</h5>
<p>Apache Storm integrates with any queueing system and any database system. Apache Storm's spout
abstraction makes it easy to integrate a new queuing system. Likewise, integrating Apache Storm
