2 What is a time series database?
Time Series Database is a special type of database used to store and process time series data. Time-series data refers to data that is arranged in time order, such as stock prices, sensor data, network traffic, weather data, etc. The main feature of a time series database is that it can efficiently store and query a large amount of time series data, and provide professional data processing and analysis functions.
Time series databases usually have the following characteristics:
-
A structured way to store time series data: Time series databases take time as the main dimension, store time series data in chronological order, and can also support data storage in other dimensions.
-
Efficient data storage and query: Time-series databases use specific data storage methods and indexing technologies to efficiently store and query large amounts of time-series data.
-
Professional data processing and analysis functions: Time series databases provide various data processing and analysis functions, such as data downsampling, sliding window calculation, data interpolation, anomaly detection, etc.
-
Support high availability and scalability: Time series databases usually have the characteristics of high availability and scalability, which can realize data backup and fault recovery, and can support large-scale data storage and query requirements through horizontal expansion.
Time-series databases are widely used in the Internet of Things, finance, electric power, energy, telecommunications, medical care and other fields, providing important support for data analysis and business decision-making.
