| <h2>Save the contents of SparkDataFrame as an ORC file, preserving the schema.</h2> |
| |
| <h3>Description</h3> |
| |
| <p>Save the contents of a SparkDataFrame as an ORC file, preserving the schema. Files written out |
| with this method can be read back in as a SparkDataFrame using read.orc(). |
| </p> |
| |
| |
| <h3>Usage</h3> |
| |
| <pre> |
| write.orc(x, path, ...) |
| |
| ## S4 method for signature 'SparkDataFrame,character' |
| write.orc(x, path, mode = "error", ...) |
| </pre> |
| |
| |
| <h3>Arguments</h3> |
| |
| <table summary="R argblock"> |
| <tr valign="top"><td><code>x</code></td> |
| <td> |
| <p>A SparkDataFrame</p> |
| </td></tr> |
| <tr valign="top"><td><code>path</code></td> |
| <td> |
| <p>The directory where the file is saved</p> |
| </td></tr> |
| <tr valign="top"><td><code>...</code></td> |
| <td> |
| <p>additional argument(s) passed to the method.</p> |
| </td></tr> |
| <tr valign="top"><td><code>mode</code></td> |
| <td> |
| <p>one of 'append', 'overwrite', 'error', 'errorifexists', 'ignore' |
| save mode (it is 'error' by default)</p> |
| </td></tr> |
