some system metadata. The serialized aspect can be in any form, though we currently default to escaped Rest.li-compatible JSON.</p><p>Callers of the V2 Aspect APIs will be expected to deserialize the aspect payload in the way they see fit. For example, they may bind the deserialized JSON object
|
|||
|
|
into a strongly typed Rest.li RecordTemplate class (which is what datahub-frontend does). The benefit of doing it this way is thaet we remove the necessity to
|
|||
|
|
use Rest.li Unions to represent an object which can take on multiple payload forms. It also makes adding and removing aspects from the model easier, a process
|
|||
|
|
which could theoretically be done at runtime as opposed to at deploy time.</p><p>To fetch a set of Timeseries Aspects that fall into a particular time range, you can use the following query template:</p><div class="codeBlockContainer_Ckt0 theme-code-block" style="--prism-color:#bfc7d5;--prism-background-color:#292d3e"><div class="codeBlockContent_biex"><pre tabindex="0" class="prism-code language-text codeBlock_bY9V thin-scrollbar"><code class="codeBlockLines_e6Vv"><span class="token-line" style="color:#bfc7d5"><span class="token plain">curl -X POST 'http://localhost:8080/aspects?action=getTimeseriesAspectValues' \</span><br></span><span class="token-line" style="color:#bfc7d5"><span class="token plain">--data '{</span><br></span><span class="token-line" style="color:#bfc7d5"><span class="token plain"> "urn": "<urn>",</span><br></span><span class="token-line" style="color:#bfc7d5"><span class="token plain"> "entity": "<entity-name>",</span><br></span><span class="token-line" style="color:#bfc7d5"><span class="token plain"> "aspect": "<time-series-aspect-name>",</span><br></span><span class="token-line" style="color:#bfc7d5"><span class="token plain"> "startTimeMillis": "<your-start-time-ms>",</span><br></span><span class="token-line" style="color:#bfc7d5"><span class="token plain"> "endTimeMillis": "<your-end-time-ms>"</span><br></span><span class="token-line" style="color:#bfc7d5"><span class="token plain">}'</span><br></span></code></pre><div class="buttonGroup__atx"><button type="button" aria-label="Copy code to clipboard" title="Copy" class="clean-btn"><span class="copyButtonIcons_eSgA" aria-hidden="true"><svg viewBox="0 0 24 24" class="copyButtonIcon_y97N"><path fill="currentColor" d="M19,21H8V7H19M19,5H8A2,2 0 0,0 6,7V21A2,2 0 0,0 8,23H19A2,2 0 0,0 21,21V7A2,2 0 0,0 19,5M16,1H4A2,2 0 0,0 2,3V17H4V3H16V1Z"></path></svg><svg viewBox="0 0 24 24" class="copyButtonSuccessIcon_LjdS"><path fill="currentColor" d="M21,7L9,19L3.5,13.5L4.91,12.09L9,16.17L19.59,5.59L21,7Z"></path></svg></span></button></div></div></div><p>For example, to fetch "datasetProfile" timeseries aspects for a dataset with urn <code>urn:li:dataset:(urn:li:dataPlatform:foo,barUp,PROD)</code>
