&lt;h3&gt;&lt;a name=&quot;Description%3A&quot;&gt;&lt;/a&gt;Description: &lt;/h3&gt;

&lt;p&gt;Remove any documentation about the 1KB index key size limit.&lt;/p&gt;

&lt;h3&gt;&lt;a name=&quot;EngineeringTicketDescription%3A&quot;&gt;&lt;/a&gt;Engineering Ticket Description:&lt;/h3&gt;

&lt;p&gt;Use the FCV mechanisms to guard the feature of unlimited index key. Things to remove include:&lt;/p&gt;
&lt;ol&gt;
	&lt;li&gt;The hardcoded size limits in the SortedDataInterface of each storage engine (wiredtiger_index.cpp, mobile_index.cpp, ephemeral_for_test_btree_impl.cpp)&lt;/li&gt;
	&lt;li&gt;The hardcoded size limit for KeyString (key_string.h)&lt;/li&gt;
	&lt;li&gt;The hardcoded size limit in index validations (record_store_validate_adaptor.cpp)&lt;/li&gt;
&lt;/ol&gt;
&lt;/div&gt;&lt;/div&gt;


&lt;h2&gt;&lt;a name=&quot;Scopeofchanges&quot;&gt;&lt;/a&gt;Scope of changes&lt;/h2&gt;

&lt;h3&gt;&lt;a name=&quot;Addblurbthatonlyfor4.2fcvorgreater.&quot;&gt;&lt;/a&gt;Add blurb that only for 4.2 fcv or greater.&lt;/h3&gt;

&lt;ul&gt;
	&lt;li&gt;limits page&lt;/li&gt;
	&lt;li&gt;4.2 &amp;amp; 4.2 compatibility&lt;/li&gt;
	&lt;li&gt;4.2downgrade&lt;/li&gt;
&lt;/ul&gt;
