Summary
In this chapter, we saw the problems caused by normal index creation, while indexing time data. You also learned how to overcome these difficulties by creating templates to create indices and overriding the default mappings and settings of indices.
We also saw how to make selective indices to be included for querying, and understood the benefits of such a feature. We also familiarized ourselves with some methods through which the old time data can be handled, as follows:
Migration of indices
Shard allocation
Optimizing indices
Closing of indices
Creating snapshots of indices
In this chapter, we saw the curator tool developed for the index management in Elasticsearch, which can be used to do most of the preceding operations.
