Roll up or transform your dataedit
Elasticsearch offers the following methods for manipulating your data:
-
Rolling up your historical data
The Elastic Stack data rollup features provide a means to summarize and store historical data so that it can still be used for analysis, but at a fraction of the storage cost of raw data.
-
Transforms enable you to convert existing Elasticsearch indices into summarized indices, which provide opportunities for new insights and analytics.
