highPerformance property

LMDBFlagSet get highPerformance

Creates a flag set optimized for high performance operations.

WARNING: This flag combination prioritizes performance over durability. It provides ACI (Atomicity, Consistency, Isolation) guarantees but NOT Durability. This means that the most recent transactions might be lost in case of a system crash.

The combination includes:

• MDB_WRITEMAP: Use writeable memory map
• MDB_MAPASYNC: Flush asynchronously
• MDB_NOSYNC: Don't flush system buffers

IMPORTANT: Thoroughly understand the implications and read the LMDB documentation before using this in production environments.

Implementation

static LMDBFlagSet get highPerformance => LMDBFlagSet()
  ..add(MDB_WRITEMAP)
  ..add(MDB_MAPASYNC)
  ..add(MDB_NOSYNC);
