Constant lmdb::WRITE_MAP
[−]
pub const WRITE_MAP: EnvironmentFlags=
EnvironmentFlags{bits: MDB_WRITEMAP,}
Use a writeable memory map unless READ_ONLY
is set. This is faster and uses
fewer mallocs, but loses protection from application bugs like wild pointer writes
and other bad updates into the database. Incompatible with nested transactions.
Processes with and without WRITE_MAP
on the same environment do not cooperate
well.
