 Description   

AT

  • given:
    • Elasticsearch, Optimze, and the engine are up runnning
    • The import of the workflow data was completed
  • when
    • a new Optimize version is up and I update Optimze
  • then
    • the old data will be removed
    • data is imported anew
    • I am able to work with old data as long as the import is not finished such that there is no downtime

Hint:
take a look at https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-aliases.html, the main ide is to create ne optimize index on every reindexing round and once it's done, associate optimize alias with it. Which will allow not to loose data during reimport process

Since we don't throw away the data after an upgrade, we don't need to do this anymore.
