Forge warnings when combining large numbers of records

When combining a large number of records (via either a Combine join or a record cache with the Combine Records setting enabled), Forge will issue a warning that performance may be slow. The default number of records at which this warning is issued is 100.

This threshold can be adjusted with the Forge --combineWarnCount command-line flag.

Two messages will be printed:

The first is an informational message that is printed when the number of records combined reaches the --combineWarnCount threshold. The message includes the key of the records being combined. The intent of this message is to give users an early warning that Forge has just started a potentially long operation and therefore may seem to be stalled, but is actually working.
The second message is a warning, indicating the total number of records combined, and the value of the key.

Note: Setting the --combineWarnCount value to 0 (zero) will disable these messages.
