}Expand description
Iterates over the KV-pairs of a given list of SSTs. The key-ranges of these SSTs are assumed to be consecutive and non-overlapping.
Fields§
§sstable_iter: Option<BlockStreamIterator>The iterator of the current table.
cur_idx: usizeCurrent table index.
sstables: Vec<SstableInfo>All non-overlapping tables.

Caller should make sure that tables are non-overlapping,
arranged in ascending order when it serves as a forward iterator,
and arranged in descending order when it serves as a backward iterator.
