Defines parameters related to lightgbm execution in spark.

chunkSize

Advanced parameter to specify the chunk size for copying Java data to native.

matrixType

Advanced parameter to specify whether the native lightgbm matrix constructed should be sparse or dense.

numThreads

The number of threads to run the native lightgbm training with on each worker.

dataTransferMode

How to transfer data to LightGBM to begin the processing.

samplingMode

How to sample data.

samplingSetSize

The size of the subset if sampling only a subset.

microBatchSize

The number of elements in a streaming micro-batch.

useSingleDatasetMode

Whether to create only 1 LightGBM Dataset on each worker.

maxStreamingOMPThreads

Maximum number of streaming mode OpenMP threads per Spark Task thread.
