&lt;p&gt;    We expect downstream impact will be needed for all teams. To be determined during scoping. &lt;/p&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;Time-series collections currently only support indexing static metadata fields. Implement support for indexing metrics that vary over time. Use cases include tracking moving vehicles, selectively indexing metrics that fall within certain geographical boundaries, and selectively deleting data for old metrics automatically.&lt;/p&gt;

&lt;h4&gt;&lt;a name=&quot;Motivation&quot;&gt;&lt;/a&gt;Motivation&lt;/h4&gt;
&lt;p&gt;Query patterns and use cases highlight the importance for customers to freely index measurement values to have better performance and accomplish the level of analysis they want to complete. Use cases such as geospatial IoT, e.g. fleet monitoring, and text searching, e.g. devops, will require users to create secondary indexes on the actual measurements being collected in time series collections.  &lt;/p&gt;

	&lt;li&gt;On the measurement field, ascending, descending, 2dsphere and partial index types will be supported.&lt;/li&gt;
