Time-Series Database
Also written as InfluxDB, TimescaleDB
A database optimized for storing and querying data points tagged with timestamps at high volume — metrics, sensor readings, logs — with built-in support for time-based aggregation and retention.
Think of it like
Like a hospital's heart-rate monitor printout, built specifically to record and later scan a continuous stream of readings over time, rather than a general filing system.
Junior or senior?
Junior sounds like
Has only queried data someone else set up in a time-series database.
Senior sounds like
Has configured retention or downsampling policies themselves.
Ask them
“Did you configure retention or downsampling policies yourself for a time-series database, or just query data someone else set up?”
