> This is another ticket that is split from https://issues.apache.org/jira/browse/IGNITE-26294. During segment file compaction we need to create new index files. The easiest way is to create a temporary memtable and save it using the existing code in the index manager. However, we only have on memtable implementation which is multi-threaded and uses stripes - this is a bit of an overkill, we only need a simple hash map in this case.
