Struct GroupSpec 

pub struct GroupSpec {
    pub group_id: String,
    pub attn_kind: String,
    pub rows_per_page: Option<i64>,
    pub entry_stride_tokens: Option<i64>,
    pub sliding_window_tokens: Option<i64>,
    pub replayable: bool,
    pub transfer_policy: Option<String>,
    pub shard_count: i64,
}

One cache group’s scheduler-facing semantics (CacheGroupSpec).

Fields

group_id: String

The group.

attn_kind: String

full_history, sliding_window or state.

rows_per_page: Option<i64>

Rows per page; row-geometry groups only.

entry_stride_tokens: Option<i64>

Raw tokens per row; row-geometry groups only.

sliding_window_tokens: Option<i64>

The retained window of a sliding-window group.

replayable: bool

A sliding-window group regenerated by bounded replay.

transfer_policy: Option<String>

full_suffix or latest_snapshot.

shard_count: i64

Cyclic owners of the group’s virtual blocks; 1 is replicated.

Implementations

impl GroupSpec

pub fn block_granularity(&self) -> Result<i64, LayoutError>

The raw-token span of one block-table slot (block_granularity); a state group has none.

pub fn full_suffix(&self) -> bool

Whether the group transfers its retained history suffix (else its latest snapshot).
