   Tickets are used for synchronizing asynchronous operations on the TripleRush index.

   Tickets are used for synchronizing asynchronous operations on the TripleRush index. An operation starts out with an initial number of tickets. The tickets are split up between sub-operations on the index and returned by each sub-operation upon completion of that operation.

   If the initial tickets are not enough the sub-operation is not executed and it returns its tickets number multiplied by -1. This means that the minus prefix indicates that the asynchronous operation could not be completed, for example because the number of tickets was too low or the branching factor of the index operation too high.

   The initial ticket values can only ever be positive, so it is impossible for a correctly working component to return Long.MinValue as the number of tickets.
