Fields

key_range: KeyRange

cache_policy: CachePolicy

gc_delete_keys: bool

retain_multiple_version: bool

stats_target_table_ids: Option<HashSet<u32>>

stats_target_table_ids decides whether a dropped key should be counted as table stats change. For an divided SST as input, a dropped key shouldn’t be counted if its table id doesn’t belong to this divided SST. See Compactor::compact_and_build_sst.

task_type: PbTaskType

use_block_based_filter: bool

table_vnode_partition: BTreeMap<u32, u32>

table_schemas: HashMap<u32, PbTableSchema>

TableId -> TableSchema Schemas in table_schemas are at least as new as the one used to create input_ssts. For a table with schema existing in table_schemas, its columns not in table_schemas but in input_ssts can be safely dropped.

disable_drop_column_optimization: bool

disable_drop_column_optimization should only be set in benchmark.
