Detailed Description

Represents one record in our key-value store.

This layout is used in all storage types for "value" part.

Attention

Do NOT instantiate this object or derive from this class. A record is always reinterpret-ed from a data page. No meaningful RTTI nor copy/move semantics.

Member Data Documentation

xct::RwLockableXctId foedus::storage::Record::owner_id_

This indicates the transaction that most recently modified this record.

This is also used as lock/delete flag. Thus, for atomic operations, Record object must be 8-byte aligned.

char foedus::storage::Record::payload_[8]

Arbitrary payload given by the user.

The size is actually meaningless (8 is just to not confuse compiler variable layout).
