Upon conflict detection, an elastic transaction might drop what it did so far within a separate transaction that immediately commits, and initiate a new transaction which might itself be elastic. Elastic transactions are a complementary alternative to traditional transactions, particularly appealing when implementing search structures. Elastic transactions can be safely composed with normal ones, but significantly improve performance if used instead.text::conference output::conference proceedings::conference paper
