title: How does Hive stores data and what is SerDe?
body: <p>when querying a table, a SerDe will <strong>deserialize a row of data from the bytes in the file to objects used internally by Hive to operate on that row of data</strong>. when performing an INSERT or CTAS (see “Importing Data” on page 441), the table’s SerDe will <strong>serialize Hive’s internal representation of a row of data into the bytes that are written to the output file</strong>.</p>
