            <title>[COMPASS-7510] Investigate changes in PM-3167: Time Series Queries Via Block Processing Container Stages in SBE</title>
                <link>https://jira.mongodb.org/browse/COMPASS-7510</link>
                <project id="13182" key="COMPASS">Compass </project>
                    <description>    &lt;div class=&quot;panel&quot; style=&quot;background-color: #c2d2c2;border-width: 1px;&quot;&gt;&lt;div class=&quot;panelHeader&quot; style=&quot;border-bottom-width: 1px;background-color: #239eb0;&quot;&gt;&lt;b&gt;Original Downstream Change Summary&lt;/b&gt;&lt;/div&gt;&lt;div class=&quot;panelContent&quot; style=&quot;background-color: #c2d2c2;&quot;&gt;
&lt;p&gt;    For time series queries that  are now eligible for lowering to SBE, the explain output will change to reflect  executing the pipelines in the new engine.&lt;/p&gt;
&lt;h2&gt;&lt;a name=&quot;DescriptionofLinkedTicket&quot;&gt;&lt;/a&gt;Description of Linked Ticket&lt;/h2&gt;
    &lt;div class=&quot;panel&quot; style=&quot;background-color: #e3fcf7;border-color: #00684a;border-style: solid;border-width: 2px;&quot;&gt;&lt;div class=&quot;panelHeader&quot; style=&quot;border-bottom-width: 2px;border-bottom-style: solid;border-bottom-color: #00684a;background-color: #00684a;&quot;&gt;&lt;b&gt;Epic Summary&lt;/b&gt;&lt;/div&gt;&lt;/div&gt;

&lt;h4&gt;&lt;a name=&quot;Summary&quot;&gt;&lt;/a&gt;Summary&lt;/h4&gt;

&lt;p&gt;Block Processing Spike has started proving key design concepts about the new block-at-a-time model, including its compatibility with MQL semantics. In this project, one mature block processing component, ie the container stages, would be designed, implemented and integrated with Time Series Bucket Collection access paths, ie collection and index scans.&lt;/p&gt;

&lt;h4&gt;&lt;a name=&quot;Motivation&quot;&gt;&lt;/a&gt;Motivation&lt;/h4&gt;

&lt;p&gt;Ultimate goal is to improve analytical query performance by investing in more efficient query execution models. This new model will first be applied to Time Series queries.&#160;This project will start developing proven concept and integrating with the first usecase - Time Series queries. These queries can then benefit from both the strength of the improved SBE as well as the block processing model.&lt;/p&gt;

&lt;p&gt;&lt;b&gt;Documentation&lt;/b&gt;&lt;/p&gt;
