<p>
The <codeph>DEFAULT_HINTS_INSERT_STATEMENT</codeph> query option sets the default hints
for the <codeph>INSERT</codeph> statements with no optimizer hint specified.
</p>
<p>
When there are hints specified in an <codeph>INSERT</codeph> statement, these default
hints are ignored.
</p>
<p>
You can specify multiple hints separated by '<codeph>:</codeph>'.
</p>
<p>
For example:
</p>
<codeblock>SET DEFAULT_HINTS_INSERT_STATEMENT=CLUSTERED;
SET DEFAULT_HINTS_INSERT_STATEMENT=SHUFFLE;
SET DEFAULT_HINTS_INSERT_STATEMENT=NOCLUSTERED:NOSHUFFLE; </codeblock>
<p>
The default hints apply to the HDFS and Kudu table formats and are ignored for the HBase
table format.
