-Specifies the number of bulk copy operations that can be performed in parallel. The maximum number of threads and ODBC connections that exist simultaneously is the lesser of `MaxBcpThreads` or the number of bulk copy requests that appear in the synchronization transaction in the distribution database. `MaxBcpThreads` must have a value greater than `0` and has no hard-coded upper limit. The default is `2` times the number of processors, up to a maximum value of `8`. When applying a snapshot that was generated at the Publisher using the concurrent snapshot option, one thread is used, regardless of the number you specify for `MaxBcpThreads`.
