| spark.plugins | To load Gluten's components by Spark's plug-in loader | io.glutenproject.GlutenPlugin |
| spark.shuffle.manager | To turn on Gluten Columnar Shuffle Plugin | org.apache.spark.shuffle.sort.ColumnarShuffleManager |
| spark.gluten.enabled | Enable Gluten, default is true. Just an experimental property. Recommend to enable/disable Gluten through the setting for `spark.plugins`. | true |
| spark.gluten.sql.advanced.cbo.enabled | Experimental: Enables Gluten's advanced CBO features during physical planning. E.g, More efficient fallback strategy, etc. The option can be turned on and off individually despite vanilla Spark's CBO settings. Note, Gluten's query optimizer may still adopt a subset of its advanced CBO capabilities even this option is off. Enabling it would cause Gluten consider using CBO for optimization more aggressively. Note, this feature is still in development and may not bring performance profits. | false |
| spark.gluten.sql.columnar.maxBatchSize | Number of rows to be processed in each batch. Default value is 4096. | 4096 |
| spark.gluten.memory.isolation | (Experimental) Enable isolated memory mode. If true, Gluten controls the maximum off-heap memory can be used by each task to X, X = executor memory / max task slots. It's recommended to set true if Gluten serves concurrent queries within a single session, since not all memory Gluten allocated is guaranteed to be spillable. In the case, the feature should be enabled to avoid OOM. Note when true, setting spark.memory.storageFraction to a lower value is suggested since storage memory is considered non-usable by Gluten. | false |
| spark.gluten.sql.columnar.scanOnly | When enabled, this config will overwrite all other operators' enabling, and only Scan and Filter pushdown will be offloaded to native. | false |
