wal_enabled_set: bool

Whether wal_enabled was explicitly set

sync_mode: u8

Sync mode: 0=OFF, 1=NORMAL (default), 2=FULL

sync_mode_set: bool

Whether sync_mode was explicitly set

memtable_size_bytes: u64

Memtable size in bytes (0 = default 64MB)

group_commit: bool

Enable group commit for throughput (default: true if group_commit_set is false)

group_commit_set: bool

Whether group_commit was explicitly set

default_index_policy: u8

Default index policy: 0=WriteOptimized, 1=Balanced (default), 2=ScanOptimized, 3=AppendOnly

default_index_policy_set: bool

Whether default_index_policy was explicitly set
