Fields§

§object_id: TypedId<5, u64>§sst_id: TypedId<6, u64>§key_range: Option<KeyRange>§file_size: u64

represents the physical object size, which is usually used in the builder.

§table_ids: Vec<TypedId<0, u32>>§meta_offset: u64§stale_key_count: u64§total_key_count: u64§min_epoch: u64§max_epoch: u64§uncompressed_file_size: u64§range_tombstone_count: u64§bloom_filter_kind: i32
👎Deprecated

Legacy SST filter metadata for SSTs written before filter_type and filter_layout existed. New writers must leave this field as BLOOM_FILTER_UNSPECIFIED and set filter_type instead.

§sst_size: u64

In order to calculate more finely in the compaction strategy, we need to re-calculate the sst_size after split sst sst_size represents the size of the sst instead of the object size(usually used in the meta).

§vnode_statistics: Option<VnodeStatistics>

Optional per-vnode statistics for query pruning when the SST spans only a small set of vnodes. Only emitted when SST contains multiple vnodes to avoid redundancy with key_range.

§filter_type: Option<i32>

Canonical SST filter type for newly written SSTs. If this field is present, bloom_filter_kind must be BLOOM_FILTER_UNSPECIFIED.

§filter_layout: Option<i32>

Canonical SST filter physical layout for newly written SSTs. This is set only when filter_type is not SSTABLE_FILTER_NONE.
