Struct SystemConfig 

pub struct SystemConfig {
    pub buffer_pool_size: u64,
    pub max_num_threads: u64,
    pub enable_compression: bool,
    pub read_only: bool,
    pub max_db_size: u64,

Configuration for the database.

Fields

buffer_pool_size: u64

max_num_threads: u64

enable_compression: bool

read_only: bool

max_db_size: u64

auto_checkpoint: bool

checkpoint_threshold: i64

concurrent_writes: bool

When true, multiple write transactions can run concurrently. When false, only one write transaction at a time is allowed.

spill_threshold: u64

Memory threshold (in bytes) for triggering disk spilling during bulk ingest (COPY FROM, large batch inserts).

When a NodeGroup’s estimated in-memory size exceeds this value, its data is spilled to a temp file and the in-memory buffer is cleared. After all rows are ingested, spilled files are merged back into persistent storage.

Default: 80% of buffer_pool_size. Set to 0 to disable spilling.
