Expand description

Transactions are the only way make changes to the ref store in order to increase the chance of consistency in a multi-threaded environment.

Transactions currently allow to…

  • create or update reference
  • delete references

The following guarantees are made:

  • transactions are prepared which is when other writers are prevented from changing them
    • errors during preparations will cause a perfect rollback
  • prepared transactions are committed to finalize the change
    • errors when committing while leave the ref store in an inconsistent, but operational state.
