Tímaröðargagnagrunnur

Tímaröðargagnagrunnur is an Icelandic term that translates to "time-series database" in English. A time-series database is a specialized database that is optimized for handling time-stamped data, also known as time-series data. This type of data consists of sequences of data points indexed in chronological order. Examples include sensor readings, stock prices, system metrics, and application performance logs.

The core principle behind a time-series database is its efficient storage and retrieval of data that is inherently ordered by time. Unlike traditional relational databases, time-series databases are designed to ingest and query large volumes of data with a time component very rapidly. They often employ techniques such as data compression, specialized indexing, and data retention policies to manage the continuous influx of time-stamped information.

Key features and benefits of time-series databases include high ingest rates, fast query performance for time-based aggregations and analysis, efficient storage utilization, and built-in functionalities for handling time-related operations like downsampling, aggregation, and windowing. These databases are particularly useful for applications that require monitoring, analyzing, and reacting to data as it changes over time. Their use cases span a wide range of industries, including IoT, finance, IT operations, and industrial automation.
