| | spark.comet.scan.preFetch.threadNum | The number of threads running pre-fetching for CometScan. Effective if spark.comet.scan.preFetch.enabled is enabled. By default it is 2. Note that more pre-fetching threads means more memory requirement to store pre-fetched row groups. | 2 | | ||
| | spark.comet.shuffle.preferDictionary.ratio | The ratio of total values to distinct values in a string column to decide whether to prefer dictionary encoding when shuffling the column. If the ratio is higher than this config, dictionary encoding will be used on shuffling string column. This config is effective if it is higher than 1.0. By default, this config is 10.0. Note that this config is only used when `spark.comet.exec.shuffle.mode` is `jvm`. | 10.0 | | ||

As we add support for other types, do we need to update this to make it recursive so that we check for Map or Array containing struct?
