+<h2 id="distribution-operators">Distribution Operators</h2>
+
+<p>Drill uses the following operators to perform data distribution over the network:  </p>
+
+<ul>
+<li>HashToRandomExchange</li>
+<li>HashToMergeExchange</li>
+<li>UnionExchange</li>
+<li>SingleMergeExchange</li>
+<li>BroadcastExchange</li>

+
+<h2 id="join-operators">Join Operators</h2>
+
+<p>Drill uses the following operators:</p>
+
+<table><thead>
+<tr>
+<th>Operator</th>
+<th>Description</th>
+</tr>
+</thead><tbody>
+<tr>
+<td>Hash Join</td>
+<td>A Hash Join is used for inner joins, left, right and full outer joins.  A hash table is built on the rows produced by the inner child of the Hash Join.  The outer child rows are used to probe the hash table and find matches. This operator Holds the entire dataset for the right hand side of the join in memory  which could be up to 2 billion records per minor fragment.</td>
+</tr>
+<tr>
+<td>Merge Join</td>
+<td>A Merge Join is used for inner join, left and right outer joins.  Inputs to the Merge Join must be sorted. It reads the sorted input streams from both sides and finds matching rows.  This operator holds the amount of memory of one incoming record batch from each side of the join.   In addition, if there are repeating values in the right hand side of the join, the Merge Join will hold record batches for as long as a repeated value extends.</td>
+</tr>
+<tr>
+<td>Nested Loop Join</td>
+<td>A Nested Loop Join is used for certain types of cartesian joins and inequality joins.</td>
+</tr>
+</tbody></table>
+
+<h2 id="aggregate-operators">Aggregate Operators</h2>
+
+<p>Drill uses the following aggregate operators:  </p>
+
+<table><thead>
+<tr>
+<th>Operator</th>
+<th>Description</th>
+</tr>
+</thead><tbody>
+<tr>
+<td>Hash Aggregate</td>
+<td>A Hash Aggregate performs grouped aggregation on the input data by building a hash table on the GROUP-BY keys and computing the aggregate values within each group. This operator holds memory for each aggregation grouping and each aggregate value, up to 2 billion values per minor fragment.</td>
+</tr>
+<tr>
+<td>Streaming Aggregate</td>
+<td>A Streaming Aggregate performs grouped aggregation and non-grouped aggregation.  For grouped aggregation, the data must be sorted on the GROUP-BY keys.  Aggregate values are computed within each group.  For non-grouped aggregation, data does not have to be sorted. This operator maintains a single aggregate grouping (keys and aggregate intermediate values) at a time in addition to the size of one incoming record batch.</td>
