| the work performed as if this split never occurred. |
| |
| <p>The <code>fractionOfRemainder</code> should be used in a best effort manner to choose a primary |
| and residual restriction based upon the fraction of the remaining work that the current <code>DoFn.ProcessElement</code> invocation is responsible for. For example, if a <code>DoFn.ProcessElement</code> was reading a file with a restriction representing the offset range <code>[100, 200)</code> and has processed up to offset 130 with a <code>fractionOfRemainder</code> of <code>0.7</code>, the primary and residual restrictions returned would be <code>[100, 179), [179, 200)</code> |
| (note: <code>currentOffset + fractionOfRemainder * remainingWork = 130 + 0.7 * 70 = 179</code>). |
| |
| <p><code>fractionOfRemainder = 0</code> means a checkpoint is required. |
| |
| <p>The API is recommended to be implemented for a batch pipeline to improve parallel processing |
