This processor is intended to be run on the Primary Node only.

+This processor can accept incoming connections; the behavior of the processor is different whether incoming connections are provided:
+ - If no incoming connection(s) are specified, the processor will generate SQL queries on the specified processor schedule. Expression Language is supported for many fields, but no flow file attributes are available. However the properties will be evaluated using the Variable Registry.
+ - If incoming connection(s) are specified and no flow file is available to a processor task, no work will be performed.
+ - If incoming connection(s) are specified and a flow file is available to a processor task, the flow file's attributes may be used in Expression Language for such fields as Table Name and others.

The processor will keep track of the maximum value for each column that has been returned since the processor started running. Using multiple columns implies an order to the column list, and each column's values are expected to increase more slowly than the previous columns' values. Thus, using multiple columns implies a hierarchical structure of
columns, which is usually used for partitioning tables. This processor can be used to retrieve only those rows that have been added/updated since the last retrieval. Note that some JDBC types such as bit/boolean are not conducive to maintaining maximum value, so columns of these types should not be listed in this property, and will result in error(s) during processing. If no columns are provided, all rows from the table will be considered, which could have a performance impact.

+ <p>
+ The pairing of this Processor with a <a href="../org.apache.nifi.processors.standard.HandleHttpResponse/index.html">HandleHttpResponse</a> Processor
+ provides the ability to use NiFi to visually construct a web server that can carry out any functionality that is available
+ through the existing Processors. For example, one could construct a Web-based front end to an SFTP Server by constructing a

+ </p>

+ The HandleHttpRequest Processor provides several Properties to configure which methods are supported, the paths that are
