Using\testing elasticsearch in blocking mode.

[abonec]

I newbie with elasticsearch and write sample app. It works well but when I write test I need an blocking mode in respect to check results of index documents. Now I use sleep in ruby by 1 second for wait index and it works. But every one sleep my testing is will grow up in time.

Is it possible to pass some param in client which will block operations until it will indexed?

Example of sleep is here: https://github.com/abonec/eta_service/blob/1214b922493d82c3b4de7e56a217296281fa7301/spec/helpers.rb#L9-L12

Am I right it is impossible on elasticsearch server-level? According elastic/elasticsearch#1063 this feature not available since 2011 year.

Have you any idea for how to get around that to clearing tests and minimize times for awaiting?

Hi @abonec, if this is about the workflow of "index some data and immediately search it", as you would do in an integration test, just call the indices.refresh API -- have a look in the integration tests for this repository, they use it. For something more complex like a Rails app, have a look at the example applications: https://github.com/elastic/elasticsearch-rails/tree/master/elasticsearch-rails#rails-application-templates

@karmi yes. I need to add little piece of test data to ES and than rely that next query will search across all the data was added and give me a reproducible result. Am I rely that indices.refresh is a blocking operation until whole data will be searchable after that? I can't see it in the documentation neither in ES or ES.ruby.

Yes, as said, it is used for integration tests for this very repo & libraries.

See http://www.rubydoc.info/gems/elasticsearch-api/Elasticsearch/API/Indices/Actions#refresh-instance_method and https://www.elastic.co/guide/en/elasticsearch/reference/2.3/indices-refresh.html
