session stickiness #31

Closed romanchyla closed 9 years ago

romanchyla commented 9 years ago

The request (if possible) should be routed to the same instance, at least for SOLR - that means that the api needs to pass appropriate headers, andthe load balancer at AWS can decide based on that. BTW: from what I see, the sessions are not sticky for AWS (which is good, IMO), but I didn't check solr

Do you mean that requests.post(SOLR_ENDPOINT) within the /search route should always speak to the same solr instance? Is this to take advantage of solr caching? Would the fact that internally, solr cloud picks a random shard to serve a request matter?

Does duration based stickiness make sense?
