Struct InstanceConfig 

pub struct InstanceConfig {
    pub instance_id: String,
    pub role: String,
    pub id_range_start: u64,
    pub id_range_size: u64,
}

Multi-instance configuration.

Controls how this server instance participates in a multi-instance deployment. In single-instance mode (default), all settings can be left at defaults.

For multi-instance deployments:

• Each instance needs a unique instance_id
• role determines whether this instance can write (writer), only read (reader), or auto-detect
• id_range_start and id_range_size partition the node ID space to avoid collisions

Fields

instance_id: String

Unique identifier for this server instance. Auto-generated from hostname + PID if not set.

role: String

Instance role: “auto” (default), “writer”, or “reader”.

• “auto”: single-instance mode, acts as both reader and writer
• “writer”: can perform writes (ingestion, learn, update, delete)
• “reader”: read-only (search, augment, get operations only)

id_range_start: u64

Starting node ID for this instance’s ID allocation range. Each instance should have a non-overlapping range to avoid ID collisions. Default: 1_000_000 (same as single-instance).

id_range_size: u64

Size of this instance’s node ID allocation range. Default: 1_000_000_000 (1 billion IDs per instance).

Implementations

impl InstanceConfig

pub fn resolved_instance_id(&self) -> String

Resolve the instance_id. If set to “auto”, generate from hostname + PID.

pub fn can_write(&self) -> bool

Whether this instance can perform write operations.

pub fn is_reader_only(&self) -> bool

Whether this instance is a dedicated reader (no writes).
