<p>The cluster-level shard allocator tries to spread the shards of a single index
across as many nodes as possible. However, depending on how many shards and
indices you have, and how big they are, it may not always be possible to spread
shards evenly.</p>
<p>The following <em>dynamic</em> setting allows you to specify a hard limit on the total
number of shards from a single index allowed per node:</p>
<div class="variablelist">
<dl class="variablelist">
<dt>
<span class="term">
<code class="literal">index.routing.allocation.total_shards_per_node</code>
</span>
</dt>
<dd>
The maximum number of shards (replicas and primaries) that will be
allocated to a single node. Defaults to unbounded.
</dd>
</dl>
</div>
<p>You can also limit the amount of shards a node can have regardless of the index:</p>
<div class="variablelist">
<dl class="variablelist">
<dt>
<span class="term">
<code class="literal">cluster.routing.allocation.total_shards_per_node</code>
</span>
</dt>
<dd>
The maximum number of shards (replicas and primaries) that will be
allocated to a single node globally. Defaults to unbounded (-1).
</dd>
</dl>
</div>
<div class="warning admon">
<div class="icon"></div>
<div class="admon_content">
<p>These settings impose a hard limit which can result in some shards not being
allocated.</p>
<p>Use with caution.</p>
