Struct MaterializeConfig 

pub struct MaterializeConfig {
    pub mode: MaterializeMode,
    pub ref_strategy: RefStrategy,
    pub memtable_max_rows: usize,
    pub max_row_group_rows: usize,
    pub max_row_group_bytes: usize,
}

Optional materialization / ref() registration policy (materialize: in yml).

All fields are optional; omitting the whole block keeps lake-as-truth Parquet re-read and stream write mode.

Fields

mode: MaterializeMode

stream (default) | collect

ref_strategy: RefStrategy

parquet (default) | memtable

memtable_max_rows: usize

Used only when ref_strategy: memtable. Defaults to DEFAULT_MEMTABLE_MAX_ROWS.

max_row_group_rows: usize

Parquet WriterProperties max rows per row group (stream + collect writers).

max_row_group_bytes: usize

Soft flush threshold for Parquet in_progress_size (bytes).

Implementations

impl MaterializeConfig

pub fn effective_mode(&self) -> MaterializeMode

Resolve write mode: env RBT_MATERIALIZE_MODE=stream|collect overrides yml.

pub fn choose_ref_backend(&self, row_count: usize) -> RefBackend

Decide MemTable vs lake file for a model that produced row_count rows.
