Struct UnsyncData

source 
struct UnsyncData {
    table_data: HashMap<TableId, TableUnsyncData>,
    instance_table_id: HashMap<LocalInstanceId, TableId>,

Expand description

Unsync data, can be either imm or spilled sst, and some aggregated epoch information.

instance_data holds the imm of each individual local instance, and data are first added here. The aggregated epoch information (table watermarks, etc.) and the spilled sst will be added to epoch_data.
