 | carbon.query.validate.direct.query.on.datamap | true | CarbonData supports creating pre-aggregate table datamaps as an independent tables. For some debugging purposes, it might be required to directly query from such datamap tables. This configuration allows to query on such datamaps. |
 | carbon.max.driver.threads.for.block.pruning | 4 | Number of threads used for driver pruning when the carbon files are more than 100k Maximum memory. This configuration can used to set number of threads between 1 to 4. |
 | carbon.heap.memory.pooling.threshold.bytes | 1048576 | CarbonData supports unsafe operations of Java to avoid GC overhead for certain operations. Using unsafe, memory can be allocated on Java Heap or off heap. This configuration controls the allocation mechanism on Java HEAP. If the heap memory allocations of the given size is greater or equal than this value,it should go through the pooling mechanism. But if set this size to -1, it should not go through the pooling mechanism. Default value is 1048576(1MB, the same as Spark). Value to be specified in bytes. |
+| carbon.push.rowfilters.for.vector | false | When enabled complete row filters will be handled by carbon in case of vector. If it is disabled then only page level pruning will be done by carbon and row level filtering will be done by spark for vector. And also there are scan optimizations in carbon to avoid multiple data copies when this parameter is set to false. There is no change in flow for non-vector based queries. |
