How does a time series database store data?
A time series database stores data as pairs of time(s) and value(s). By storing data in this way, it makes it easy to analyze time series, or a sequence of points recorded in order over time. A TSDB can handle concurrent series, measuring many different variables or metrics in parallel.

What are the properties of time series data?
I need to store and to be able to query some very large amounts time series data. Properties of the data are as follows: Properties of envisioned queries: most of the queries against the data will be timestamp-based queries; ranging from one day to several months/years. 90%+ will be queries on the most recent data
How to efficiently store and query time series data?
As you can see, it’s really simple and straightforward: a composite index on both ticker (which references the actual financial symbol) and time, in order to minimize range table scans for specific symbols. PostgreSQL burned through the tens of millions of records I tried to load using the wonderful COPY command, with no kind of performance hit.
