> Due to recovery of SchemaManager seems we need to restore and register all

> {noformat}
> private SortedMap<Integer, byte[]> collectAllSchemas(UUID tblId) {
> Cursor<Entry> cur =
> metastorageMgr.prefix(schemaHistPrefix(tblId));
> SortedMap<Integer, byte[]> schemes = new TreeMap<>();
> for (Entry ent : cur) {
> String key = ent.key().toString();
> int descVer = extractVerFromSchemaKey(key);
> schemes.put(descVer, ent.value());
> }
> return schemes;
> }
> {noformat}
