Bolt adaptor cannot recover from neo4j restart

[beho]

Hi,

I'm using neo4j-core to acess external neo4j from very simple Sinatra-base API.

When Bolt adaptor is used and database is restarted without restart the API, next query causes ruby process to use a lot of CPU time and thus rendering API useless. I had to switch to HTTP adaptor which gracefully continues to operate when database boots up.

Runtime information:

Neo4j database version:
neo4j gem version: 3.3.4
neo4j-core gem version: 8.1.4

I believe the bolt adapter is defined here, if you're interested in figuring out what's going wrong: https://github.com/neo4jrb/neo4j-core/blob/master/lib/neo4j/core/cypher_session/adaptors/bolt.rb

I don't believe anyone, in particular, has claimed "responsibility" for maintaining the bolt adapter, so unless you are interested in fixing this issue, I think your best bet is to stick with the http adapter.
