Test build #42084 has finished for PR 8638 at commit
|
| Implementation to use for shuffling data. There are three implementations available: | ||
| <code>sort</code>, <code>hash</code> and the new <code>tungsten-sort</code>. | ||
| Sort-based shuffle is more memory-efficient and is the default option starting in 1.2. | ||
| Tungsten-sort is similar to sort based shuffle, with a direct binary cache-friendly |
There was a problem hiding this comment.
Nits: "to the sort-based". Does this need qualification as being experimental, and available from 1.5 onward?
