Fields§

§table_id: u32§columns: Vec<ColumnDesc>§pk: Vec<ColumnOrder>

TODO: may refactor primary key representations

§dist_key_in_pk_indices: Vec<u32>§value_indices: Vec<u32>§read_prefix_len_hint: u32§versioned: bool

Whether the table is versioned. If true, column-aware row encoding will be used to be compatible with schema changes.

§stream_key: Vec<u32>§vnode_col_idx_in_pk: Option<u32>§retention_seconds: Option<u32>§maybe_vnode_count: Option<u32>

Total vnode count of the table.

Can be unset if the table is created in older versions where variable vnode count is not supported, in which case a default value of 256 (or 1 for singleton) should be used. Use VnodeCountCompat::vnode_count to access it.
