+<p>A character-separated values plain-text file represents a tabular data set consisting of rows and columns.
+Each row is a plan-text line. A line is usually broken by a character line feed <code class="docutils literal"><span class="pre">\n</span></code> or carriage-return <code class="docutils literal"><span class="pre">\r</span></code>.
+The line feed <code class="docutils literal"><span class="pre">\n</span></code> is the default delimiter in Tajo. Each record consists of multiple fields, separated by
+some other character or string, most commonly a literal vertical bar <code class="docutils literal"><span class="pre">|</span></code>, comma <code class="docutils literal"><span class="pre">,</span></code> or tab <code class="docutils literal"><span class="pre">\t</span></code>.
+The vertical bar is used as the default field delimiter in Tajo.</p>

+<p>In order to specify a certain file format for your table, you need to use the <code class="docutils literal"><span class="pre">USING</span></code> clause in your <code class="docutils literal"><span class="pre">CREATE</span> <span class="pre">TABLE</span></code>

+<h2>Physical Properties<a class="headerlink" href="#physical-properties" title="Permalink to this headline">¶</a></h2>
+<p>Some table storage formats provide parameters for enabling or disabling features and adjusting physical parameters.
+The <code class="docutils literal"><span class="pre">WITH</span></code> clause in the CREATE TABLE statement allows users to set those parameters.</p>
+<p><em>TEXT</em> format provides the following physical properties.</p>
+<ul class="simple">
+<li><code class="docutils literal"><span class="pre">text.delimiter</span></code>: delimiter character. <code class="docutils literal"><span class="pre">|</span></code> or <code class="docutils literal"><span class="pre">\u0001</span></code> is usually used, and the default field delimiter is <code class="docutils literal"><span class="pre">|</span></code>.</li>
+<li><code class="docutils literal"><span class="pre">text.null</span></code>: <code class="docutils literal"><span class="pre">NULL</span></code> character. The default <code class="docutils literal"><span class="pre">NULL</span></code> character is an empty string <code class="docutils literal"><span class="pre">''</span></code>. Hive’s default <code class="docutils literal"><span class="pre">NULL</span></code> character is <code class="docutils literal"><span class="pre">'\\N'</span></code>.</li>
+<li><code class="docutils literal"><span class="pre">compression.codec</span></code>: Compression codec. You can enable compression feature and set specified compression algorithm. The compression algorithm used to compress files. The compression codec name should be the fully qualified class name inherited from <a class="reference external" href="https://hadoop.apache.org/docs/current/api/org/apache/hadoop/io/compress/CompressionCodec.html">org.apache.hadoop.io.compress.CompressionCodec</a>. By default, compression is disabled.</li>
+<li><code class="docutils literal"><span class="pre">text.serde</span></code>: custom (De)serializer class. <code class="docutils literal"><span class="pre">org.apache.tajo.storage.text.CSVLineSerDe</span></code> is the default (De)serializer class.</li>
+<li><code class="docutils literal"><span class="pre">timezone</span></code>: the time zone that the table uses for writting. When table rows are read or written, <code class="docutils literal"><span class="pre">`timestamp`</span></code> and <code class="docutils literal"><span class="pre">`time`</span></code> column values are adjusted by this timezone if it is set. Time zone can be an abbreviation form like ‘PST’ or ‘DST’. Also, it accepts an offset-based form like ‘UTC+9’ or a location-based form like ‘Asia/Seoul’.</li>
+<li><code class="docutils literal"><span class="pre">text.error-tolerance.max-num</span></code>: the maximum number of permissible parsing errors. This value should be an integer value. By default, <code class="docutils literal"><span class="pre">text.error-tolerance.max-num</span></code> is <code class="docutils literal"><span class="pre">0</span></code>. According to the value, parsing errors will be handled in different ways.
+* If <code class="docutils literal"><span class="pre">text.error-tolerance.max-num</span> <span class="pre"><</span> <span class="pre">0</span></code>, all parsing errors are ignored.
+* If <code class="docutils literal"><span class="pre">text.error-tolerance.max-num</span> <span class="pre">==</span> <span class="pre">0</span></code>, any parsing error is not allowed. If any error occurs, the query will be failed. (default)
+* If <code class="docutils literal"><span class="pre">text.error-tolerance.max-num</span> <span class="pre">></span> <span class="pre">0</span></code>, the given number of parsing errors in each task will be pemissible.</li>
+</ul>
+<p>The following example is to set a custom field delimiter, <code class="docutils literal"><span class="pre">NULL</span></code> character, and compression codec:</p>

+<div class="section" id="custom-de-serializer">
+<h2>Custom (De)serializer<a class="headerlink" href="#custom-de-serializer" title="Permalink to this headline">¶</a></h2>
+<p>The <em>TEXT</em> format not only provides reading and writing interfaces for text data but also allows users to process custom
+plan-text file formats with user-defined (De)serializer classes.
+For example, with custom (de)serializers, Tajo can process JSON file formats or any specialized plan-text file formats.</p>
+<p>In order to specify a custom (De)serializer, set a physical property <code class="docutils literal"><span class="pre">text.serde</span></code>.
+The property value should be a fully qualified class name.</p>

+<div class="section" id="null-value-handling-issues">

+<p>In default, <code class="docutils literal"><span class="pre">NULL</span></code> character in <em>TEXT</em> format is an empty string <code class="docutils literal"><span class="pre">''</span></code>.
+In other words, an empty field is basically recognized as a <code class="docutils literal"><span class="pre">NULL</span></code> value in Tajo.
+If a field domain is <code class="docutils literal"><span class="pre">TEXT</span></code>, an empty field is recognized as a string value <code class="docutils literal"><span class="pre">''</span></code> instead of <code class="docutils literal"><span class="pre">NULL</span></code> value.
+Besides, You can also use your own <code class="docutils literal"><span class="pre">NULL</span></code> character by specifying a physical property <code class="docutils literal"><span class="pre">text.null</span></code>.</p>
