[2/2] asterixdb git commit: [ASTERIXDB-2339] Add a new inverted index
merge cursor
[ASTERIXDB-2339] Add a new inverted index merge cursor
- user model changes: no
- storage format changes: no
- interface changes: no
Details:
- Implement a new inverted index merge cursor which uses two priority queues,
one for tokens and one for keys. For each token, we merge their inverted
lists using the key queue. After that, we fetch the next token and merge
their lists again. This reduces unnecessary token comparision a lot.
- Along this change, created a fast path for inverted index bulkloader.
Based on how the token+key pair is created, there is no need to copy
bulkloaded tuple and check whether it's a new token during merge.
