Struct FlushConfig 

pub struct FlushConfig {
    pub flush_threshold: usize,
    pub max_memory: usize,
    pub stall_soft_fraction: f64,
    pub max_stall_delay: Duration,
    pub max_frozen_memtables: usize,
    pub segment_dir: PathBuf,
    pub segment_writer_config: SegmentWriterConfig,
}

Configuration for the flush controller.

Fields

flush_threshold: usize

Memory threshold (bytes) that triggers a flush.

max_memory: usize

Maximum total memory across active + frozen memtables.

stall_soft_fraction: f64

Soft limit as a fraction of max_memory (0.0–1.0) at which graduated write stall begins. Below this, writes proceed without delay. Between soft limit and hard limit, writes are delayed proportionally. Default: 0.75 (delays begin at 75% of max_memory).

max_stall_delay: Duration

Maximum write stall delay applied at the hard limit boundary. Default: 100ms.

max_frozen_memtables: usize

Maximum number of frozen memtables queued for flush. When the queue is full, freeze_and_swap rejects with CapacityExceeded. Default: 2.

segment_dir: PathBuf

Directory to write segment files.

segment_writer_config: SegmentWriterConfig

Configuration for the segment writer.
