            <title>[SERVER-68763] Add performance testing to measure the performance impact of running the analyzeShardKey command</title>
                <link>https://jira.mongodb.org/browse/SERVER-68763</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Four most-used shard key patterns: single_hashed, ranged_compound, single_ranged, id_hashed&lt;/p&gt;
&lt;h1&gt;&lt;a name=&quot;Testplan&quot;&gt;&lt;/a&gt;Test plan&lt;/h1&gt;
&lt;h2&gt;&lt;a name=&quot;HowlongdoesanalyzeShardKeytaketorunbyitself&quot;&gt;&lt;/a&gt;How long does analyzeShardKey take to run by itself&lt;/h2&gt;
&lt;h3&gt;&lt;a name=&quot;withoutsamples&quot;&gt;&lt;/a&gt;without samples&lt;/h3&gt;

&lt;p&gt;T1. Run ycsb_load for {5M, 50M, 1000M} documents, followed by analyzeShardKey for {field0: 1, field1: &quot;hashed&quot;}. This will tell us whether run-time of the command is linear w.r.t. number of documents.&lt;/p&gt;

&lt;p&gt;T2. Repeat test T1 for {field0: 1}&lt;/p&gt;

&lt;p&gt;T2a. Repeat test T1 for two analyzeShardKey commands running concurrently, one command for each key.&lt;/p&gt;
&lt;h3&gt;&lt;a name=&quot;withsamples&quot;&gt;&lt;/a&gt;with samples&lt;/h3&gt;

&lt;p&gt;T3. For each of the clusters containing {50M} documents, run {30, 60} minutes of ycsb_read50update50 with sampling rate of 50/sec, followed by analyzeShardKey for {field0: 1, field1: &quot;hashed&quot;}. This will tell us how much longer the command takes to gather read/write distribution metrics.&lt;/p&gt;

&lt;p&gt;T4. Repeat test T3 for {field0: 1}&lt;/p&gt;

&lt;p&gt;T4a. Repeat test T3 for two analyzeShardKey commands running concurrently, one command for each key.&lt;/p&gt;
&lt;h2&gt;&lt;a name=&quot;HowdoesanalyzeShardKeyandquerysamplingimpactconcurrentworkloadperformance&quot;&gt;&lt;/a&gt;How does analyzeShardKey and query sampling impact concurrent workload performance&lt;/h2&gt;

&lt;p&gt;T5. Run ycsb_load for {1000M} documents, followed by a long run of ycsb_read50update50 with sampling rate of 50/sec. While ycsb_read50update50 is running, run analyzeShardKey every X minutes. (X depends on how long analyzeShardKey takes to run.)&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;
