Detailed Description
template<typename TDerived>
struct NYT::TJoinReduceOperationSpecBase< TDerived >
struct NYT::TJoinReduceOperationSpecBase< TDerived >
Spec of JoinReduce operation.
- Deprecated
- Instead the user should run a reduce operation with NYT::TReduceOperationSpec::EnableKeyGuarantee set to false.

◆ DataSizePerJob()
template<typename TDerived>
| TSelf & NYT::TJoinReduceOperationSpecBase< TDerived >::DataSizePerJob | ( | ui64 | ) |
Recommended number of jobs to run.
`JobCount' has higher priority than NYT::TJoinReduceOperationSpecBase::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::TJoinReduceOperationSpecBase::JobCount. This option only provide a recommendation and may be ignored if conflicting with YT internal limits.
◆ JoinBy()
template<typename TDerived>
| TSelf & NYT::TJoinReduceOperationSpecBase< TDerived >::JoinBy | ( | TSortColumns | ) |
Columns to join foreign tables by (must be prefix of ReduceBy).
