Row Traversal Types

The “Row traversal type” setting specifies how each server will traverse its slice of the seed data.

  • Sequential

The server traverses through it’s set of data sequentially. The “EOF Action” setting applies and indicates what to do if the end of the server’s set of data is reached.

  • Random with replacement

Whenever a new value is needed to fill in a new property value, one is chosen randomly from the server’s set of data. The “EOF Action” setting does not apply, since each selection is just made randomly from the entire set of data for that server, and therefore the server can never “run out” of values.

  • Random without replacement

Whenever a new value is needed, one is chosen at random and marked as used. Thus a unique value is chosen each time from the server’s set of data. Since in this case the server can run out of data, the “EOF Action” setting applies.
