A database monitoring operation and maintenance method and system based on time series data compression

The application provides a database monitoring operation and maintenance method and system based on time series data compression, which realizes real-time monitoring of various index data of a database platform through efficient data acquisition and compression technology. The system can efficiently collect various performance data generated during the operation of the database, and optimize the time series data through a compression algorithm to reduce the redundant storage of data.
