Can someone please help me understand
- What is the current back end storage engine used in Couchbase Server 6.x enterprise edition? Is it CouchDB based CouchStore or Magma?
- What is the current file storage format used by the storage engine? B+ Tree based or an LSM based SSTable format?
- What is the compaction strategy used to compact the Couchbase buckets? Is it a Level based or Size based or any other compaction strategy?
- What is the index storage format for Global Secondary Indexes in memory and on disk? I understand its Nitro based skip list in memory. What does it look like on disk for data greater than memory scenarios?
