For write throughput, TSDB's generally outperform Elasticsearch by five-10x depending on the schema and the Time Series Database. Query speed on particular time series is five-100x worse with Elasticsearch than with a TSDB depending on the variety of time becoming queried. Ultimately, on-disk size is ten-15x larger on Elasticsearch than with most Time Series Databases if you want to query the raw information later. If making use of a config that summarizes the information just before it goes into the database, Elasticsearch's on-disk size is 3-4x larger than a Time Series Database.
