 <a name="sql.multiThreadedRead.numThreads"></a>spark.rapids.sql.multiThreadedRead.numThreads|The maximum number of threads on each executor to use for reading small files in parallel. This can not be changed at runtime after the executor has started. Used with COALESCING and MULTITHREADED readers, see spark.rapids.sql.format.parquet.reader.type, spark.rapids.sql.format.orc.reader.type, or spark.rapids.sql.format.avro.reader.type for a discussion of reader types. If it is not set explicitly and spark.executor.cores is set, it will be tried to assign value of `max(MULTITHREAD_READ_NUM_THREADS_DEFAULT, spark.executor.cores)`, where MULTITHREAD_READ_NUM_THREADS_DEFAULT = 20.|20|Startup
 <a name="sql.reader.batchSizeBytes"></a>spark.rapids.sql.reader.batchSizeBytes|Soft limit on the maximum number of bytes the reader reads per batch. The readers will read chunks of data until this limit is met or exceeded. Note that the reader may estimate the number of bytes that will be used on the GPU in some cases based on the schema and number of rows in each batch.|2147483647|Runtime
 <a name="sql.reader.batchSizeRows"></a>spark.rapids.sql.reader.batchSizeRows|Soft limit on the maximum number of rows the reader will read per batch. The orc and parquet readers will read row groups until this limit is met or exceeded. The limit is respected by the csv reader.|2147483647|Runtime
