Hi All, We are indexing streaming data into ES. I would like to know about the ideal optimize strategy for our usecase. Also, we have required to delete historical indices and index mapping. As we will delete the indices and index mapping, the disk space will free only after running the optimize command. Please suggest an ideal optimize approach?

True if you delete mapping. Wrong if you delete index. Delete the full index if you can. It is really really faster than deleting a mapping (means deleting all docs for this type). Basically, it's a rm -rf on each node which is extremly fast and frees your disk space immediatly. -- David 😉 Twitter : @dadoonet / @elasticsearchfr / @scrutmydocs Le 17 juin 2013 à 07:48, Ankit Jain [ankitjaincs06@gmail.com](mailto:ankitjaincs06@gmail.com) a écrit : Hi All, We are indexing streaming data into ES.
