Member Data Documentation

std::atomic<Epoch::EpochInteger> foedus::log::LogManagerControlBlock::durable_global_epoch_

The durable epoch of the entire engine.

Invariant

current_global_epoch_ > durable_global_epoch_ (we need to advance current epoch to make sure the ex-current epoch is durable)

This value indicates upto what commit-groups we can return results to client programs. This value is advanced by checking the durable epoch of each logger.
