◆ DataSizePerJob()
| TSelf & NYT::TMergeOperationSpec::DataSizePerJob | ( | ui64 | ) |
Recommended number of jobs to run.
`JobCount' has higher priority than NYT::TMergeOperationSpec::DataSizePerJob. This option only provide a recommendation and may be ignored if conflicting with YT internal limits. */ TSelf& JobCount ( ui32 ); ;
/**
Recommended of data size for each job.
DataSizePerJob has lower priority that NYT::TMergeOperationSpec::JobCount. This option only provide a recommendation and may be ignored if conflicting with YT internal limits.
◆ SchemaInferenceMode()
| TSelf & NYT::TMergeOperationSpec::SchemaInferenceMode | ( | ESchemaInferenceMode | ) |
Inference mode for output table schema.
