+
+ <p>Drill 1.9 introduces an asynchronous Parquet reader option that you can enable to improve the performance of the Parquet Scan operator. The Parquet Scan operator reads Parquet data. Reading Parquet data involves scanning the disk, decompressing and decoding the data, and writing data to internal memory structures (value vectors). </p>
+
+<p>When the asynchronous parquet reader option is enabled, the speed at which the Parquet reader scans, decompresses, and decodes the data increases. The scan operation uses a buffering read strategy that allows the file system to perform larger, sequential reads, which significantly improves query performance. </p>
+
+<p>Typically, the Drill default settings provide the best performance for a wide variety of use cases. However, specific cases that require a high level of performance can benefit from tuning the Parquet Scan operator. </p>
+
+<h2 id="tuning-the-parquet-scan-operator">Tuning the Parquet Scan Operator</h2>
+
+<p>The <code>store.parquet.reader.pagereader.async</code> option turns the asynchronous Parquet reader on or off. The option is turned on by default. You can use the <a href="/docs/alter-session-command/">ALTER SESSION SET command</a> to enable the asynchronous Parquet reader option, as well as the options that control buffering and parallel decoding. </p>
+
+<p>When the asynchronous Page reader option is enabled, the Parquet Scan operator no longer reports operator wait time. Instead, it reports additional operator metrics that you can view in the query profile in the Drill Web Console. </p>
+
+<p>The <code>drill.exec.scan.threadpool_size</code> and <code>drill.exec.scan.decode_threadpool_size</code> parameters in the <code>drill-override.conf</code> file control the size of the threadpools that read and decode Parquet data when the asynchronous Parquet reader is enabled. </p>
+
+<p>For more information, see the <a href="https://github.com/parthchandra/drill/wiki/Parquet-file-reading-performance-improvement">functional specification</a>. </p>

+
+<p>The asynchronous Parquet reader option can increase the amount of memory required to read a single column of Parquet data up to 8MB. When the data in a column is less than 8MB, the reader uses less memory. Therefore, if a Parquet file has many columns (hundreds of columns), each column should have less than 8MB of data in each column. </p>
