Optimize for read-only explicit transactions

    • Type: Icon: Task Task
    • Resolution: Done
    • WT2.2
    • Affects Version/s: None
    • Component/s: None

      If an application calls begin_transaction but only performs queries, there is no need to allocate a transaction ID. Defer allocating the ID until the first update is performed. This should allow the read-only optimization in __wt_txn_refresh to kick in.
