I tried to create an index on one collection to optimize a query. The collection got 85m documents. However after I started to building the index, it showed 320m mutations remaining. I’ve already compacted the bucket and there was no updates to the collection after compaction.
I am wondering why there were almost 4 times of documents for the number of mutations the index need to go through.
I am using Enterprise Edition 7.1 in this test.
