| <p>CQL distinguishes between <em>reserved</em> and <em>non-reserved</em> keywords. |
| Reserved keywords cannot be used as identifier, they are truly reserved |
| for the language (but one can enclose a reserved keyword by |
| double-quotes to use it as an identifier). Non-reserved keywords however |
| only have a specific meaning in certain context but can used as |
| identifier otherwise. The only <em>raison d’être</em> of these non-reserved |
| keywords is convenience: some keyword are non-reserved when it was |
| always easy for the parser to decide whether they were used as keywords |
| or not.</p> |

| <p>Starting version 4.0, Thrift and COMPACT STORAGE is no longer supported.</p> |
| <p>‘ALTER … DROP COMPACT STORAGE’ statement makes Compact Tables CQL-compatible, |
| exposing internal structure of Thrift/Compact Tables:</p> |
| <ul class="simple"> |
| <li>CQL-created Compact Tables that have no clustering columns, will expose an |
| additional clustering column <code class="docutils literal notranslate"><span class="pre">column1</span></code> with <code class="docutils literal notranslate"><span class="pre">UTF8Type</span></code>.</li> |
| <li>CQL-created Compact Tables that had no regular columns, will expose a |
| regular column <code class="docutils literal notranslate"><span class="pre">value</span></code> with <code class="docutils literal notranslate"><span class="pre">BytesType</span></code>.</li> |
| <li>For CQL-Created Compact Tables, all columns originally defined as |
| <code class="docutils literal notranslate"><span class="pre">regular</span></code> will be come <code class="docutils literal notranslate"><span class="pre">static</span></code></li> |
| <li>CQL-created Compact Tables that have clustering but have no regular |
| columns will have an empty value column (of <code class="docutils literal notranslate"><span class="pre">EmptyType</span></code>)</li> |
| <li>SuperColumn Tables (can only be created through Thrift) will expose |
| a compact value map with an empty name.</li> |
| <li>Thrift-created Compact Tables will have types corresponding to their |
| Thrift definition.</li> |
