Use of Transactions

ActiveSpaces supports transactions to keep data consistent, even in cases of system failure.

• Transaction Methods
  Since in ActiveSpaces transactions can span operations on more than one space, users need to specify the start and the end of a transaction using the metaspace’s beginTransaction, commit, or rollback methods.
• Space Operation Options
  Many space operations can be combined with various options. Options can be used to optimize performance of the space operations, by either combining two operations together or indicating whether the return value is unwanted.
