                            <comment id="2960913" author="anton.korshunov" created="Tue, 10 Mar 2020 16:19:03 +0000"  >&lt;p&gt;After spending a sprint working on sort performance, I got back to SBE work. Here is an update for the last couple weeks:&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;Committed an initial implementation for the SBE multi-planner.&lt;/li&gt;
	&lt;li&gt;Added a further improvement to better handle plan stage trees with a blocking sort stage.&lt;/li&gt;
	&lt;li&gt;Doing a bit more testing now.&lt;/li&gt;
	&lt;li&gt;Started looking at caching of SBE plans.&lt;/li&gt;
&lt;/ul&gt;

&lt;ul&gt;
	&lt;li&gt;Added foundation to translate projection expressions.&lt;/li&gt;
	&lt;li&gt;Implemented constant and $add expressions.&lt;/li&gt;
	&lt;li&gt;Implemented field path expressions traversal.&lt;/li&gt;
	&lt;li&gt;Added support for exclusion projections.&lt;/li&gt;
	&lt;li&gt;Started working on the multi-planner.&lt;/li&gt;
&lt;/ul&gt;
