-<h2>Spark project improvement proposals (SPIP)</h2>
-
 The purpose of an SPIP is to inform and involve the user community in major improvements to the Spark codebase throughout the development process, to increase the likelihood that user needs are met.
 
 SPIPs should be used for significant user-facing or cross-cutting changes, not small incremental improvements. When in doubt, if a committer thinks a change needs an SPIP, it does.

 This page describes the advantages of the pandas API on Spark (“pandas on Spark”) and when you should use it instead of pandas (or in conjunction with pandas).
 
 pandas on Spark can be much faster than pandas and offers syntax that is familiar to pandas users.  It offers the power of Spark with the familiarity of pandas.
