          <p>Shrink an index.
          Shrink an index into a new index with fewer primary shards.</p>
          <p>Before you can shrink an index:</p>
          <ul>
          <li>The index must be read-only.</li>
          <li>A copy of every shard in the index must reside on the same node.</li>
          <li>The index must have a green health status.</li>
          </ul>
          <p>To make shard allocation easier, we recommend you also remove the index's replica shards.
          You can later re-add replica shards as part of the shrink operation.</p>
          <p>The requested number of primary shards in the target index must be a factor of the number of shards in the source index.
          For example an index with 8 primary shards can be shrunk into 4, 2 or 1 primary shards or an index with 15 primary shards can be shrunk into 5, 3 or 1.
          If the number of shards in the index is a prime number it can only be shrunk into a single primary shard
          Before shrinking, a (primary or replica) copy of every shard in the index must be present on the same node.</p>
          <p>The current write index on a data stream cannot be shrunk. In order to shrink the current write index, the data stream must first be rolled over so that a new write index is created and then the previous write index can be shrunk.</p>
          <p>A shrink operation:</p>
          <ul>
          <li>Creates a new target index with the same definition as the source index, but with a smaller number of primary shards.</li>
          <li>Hard-links segments from the source index into the target index. If the file system does not support hard-linking, then all segments are copied into the new index, which is a much more time consuming process. Also if using multiple data paths, shards on different data paths require a full copy of segment files if they are not on the same disk since hardlinks do not work across disks.</li>
          <li>Recovers the target index as though it were a closed index which had just been re-opened. Recovers shards to the <code>.routing.allocation.initial_recovery._id</code> index setting.</li>
          </ul>
          <p>IMPORTANT: Indices can only be shrunk if they satisfy the following requirements:</p>
          <ul>
          <li>The target index must not exist.</li>
          <li>The source index must have more primary shards than the target index.</li>
          <li>The number of primary shards in the target index must be a factor of the number of primary shards in the source index. The source index must have more primary shards than the target index.</li>
          <li>The index must not contain more than 2,147,483,519 documents in total across all shards that will be shrunk into a single shard on the target index as this is the maximum number of docs that can fit into a single shard.</li>
          <li>The node handling the shrink process must have sufficient free disk space to accommodate a second copy of the existing index.</li>
          </ul>
