> What it does:
> * Write a “truncate prefix marker” entry into the segment.
> * Delete data from mem-table if it matches requested raft indexes.
> * If truncation affects the “GroupMetadata” queue, then remove mentions of
> truncated entries from “IndexMeta[]” list and the corresponding “IndexMeta”
> elements.
> Segment files and index files are not physically deleted yet, this part will
> be implemented separately.
