Time series storage

When we need to store information describing the operation of assets at certain moments over a period of time (for example, information from asset sensors), the best choice is a time series storage. Currently, there are dozens of such databases to choose from. The table here features a comparison of the most widely used ones:

DalmatinerDB	InfluxDB	Prometheus	Elasticsearch	Graphite (Whisper)
Data types	float62, int56	int64, float64, bool, and string	float64	string, int32, int64, float32, float64, bool, null	float64
Data compression ratio	1	2.2	1.3	22	12
Precision	millisecond	nanosecond	millisecond	millisecond	second
Ingest performance (metrics/sec)	3m	470k ...
