Apache IoTDB (Database for Internet of Things) is an IoT native database with high performance for data management and analysis, deployable on the edge and the cloud. Due to its light-weight architecture, high performance and rich feature set together with its deep integration with Apache Hadoop, Spark and Flink, Apache IoTDB can meet the requirements of massive data storage, high-speed data ingestion and complex data analysis in the IoT industrial fields.
Hexagonal hierarchical geospatial indexing system.
H3 is a geospatial indexing system using a hexagonal grid that can be (approximately) subdivided into finer and finer hexagonal grids, combining the benefits of a hexagonal grid with S2's hierarchical subdivisions.
This book uses MySQL challenges as case studies to explore problem analysis and resolution strategies. Readers will gain a deeper appreciation for logical reasoning, data structures, algorithms, and more through practical examples and insightful discussions.
Upon first encountering SQL after two decades of Fortran, C, Java, and Python, I thought I had stumbled into hell. I quickly realized that was optimistic: after all, hell has rules.
I have since realized that SQL does too, and that they are no more confusing or contradictory than those of most other programming languages. They only appear so because it draws on a tradition unfamiliar to those of us raised with derivatives of C. To quote Terry Pratchett, it is not mad, just differently sane.
Welcome, then, to a world in which the strange will become familiar, and the familiar, strange. Welcome, thrice welcome, to SQL.
PGTune calculate configuration for PostgreSQL based on the maximum performance for a given hardware configuration.
It isn't a silver bullet for the optimization settings of PostgreSQL. Many settings depend not only on the hardware configuration, but also on the size of the database, the number of clients and the complexity of queries. An optimal configuration of the database can only be made given all these parameters are taken into account.
