The default implementation of google guava cache is in-memory. Does elasticsearch override this default behavoir? If not, please some one tell me how to make cache persistable probably to index reposioty itself when the cached values are complex objects -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Hi, There are several caches in Elasticsearch, the main ones being the filter cache and the field data cache. Storing the filter cache on disk makes little sense because in most cases it would make the cached filters almost as slow to load as the original filters. Regarding field data, it is not possible to have disk-based field data implementations in current releases but there is ongoing work towards that direction so this feature will hopefully be available in a future elasticsearch release. -- Adrien Grand -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
