[GitHub] [couchdb] nickva opened a new pull request #3447: Decrease the view indexer transaction time
nickva opened a new pull request #3447:
URL: https://github.com/apache/couchdb/pull/3447
The indexer ransaction time is decreased in order to allow enough time for the client to re-use the same GRV to emit doc bodies.
This PR goes along with [1], where emitted doc bodies in a view responses now come from the same database read version as the one used by the indexer. Since the batcher previously used 4.5 seconds as the maximum, that left little time to read any doc bodies.

The default behavior was characterized by @davisp during the initial PR for the new batcher: https://github.com/apache/couchdb/pull/3127#issue-478920470
During overload, especially if using a remote `couch_eval` instances like [ateles](https://github.com/cloudant-labs/ateles), the retries or any slowdowns there would also be counted against the TX time, that is something to worry about.
