MDB_NOMETASYNC top-level constant

int const MDB_NOMETASYNC

Don't sync meta pages when committing transaction.

When used:

• Provides middle ground between sync and async commits
• Still flushes file system buffers
• Better performance than full sync

Common usage scenarios:

• Production systems needing balance of safety/speed
• When full MDB_NOSYNC is too risky
• High-performance requirements with some safety

Example:

    await db.init(path,
        flags: LMDBFlagSet()..add(MDB_NOMETASYNC));

Comparison:

• Safer than MDB_NOSYNC
• Slower than MDB_NOSYNC
• Faster than default sync behavior

Implementation

const MDB_NOMETASYNC = bindings.MDB_NOMETASYNC;
