Database optimized for storing and querying time-stamped data like sensor readings or metrics. Like a specialized filing system designed for tracking how things change over time.
Manufacturing companies use time series databases to store and analyze machine performance data over months and years.
Amazon Timestream is a purpose-built time series database. Azure Data Explorer is an analytics database commonly used for time-stamped logs/telemetry with KQL. Cloud Bigtable is a wide-column database often used to store time series at scale (schema design is on you). OCI does not have a direct, purpose-built time series database service; OCI Streaming is an event ingestion service often paired with a database/analytics store for time series analysis.
