Structs
- This struct will be backed by mmaped and snapshotted data files. So the data layout must be stable and consistent across the entire cluster!
- A thread-safe, file-backed block of memory used to store
Account
instances. Append operations are serialized such that only one thread updates the internalappend_lock
at a time. No restrictions are placed on reading. That is, one may read items from one thread while another is appending new items. - References to account data stored elsewhere. Getting an
Account
requires cloning (seeStoredAccountMeta::clone_account()
). - Meta contains enough context to recover the index from storage itself This struct will be backed by mmaped and snapshotted data files. So the data layout must be stable and consistent across the entire cluster!
