This repository contains a revision of the GridDB documentation.
GridDB is an open source time-series database with the speed of NoSQL and convenience of SQL. It is optimized for Industrial IoT and Big Data workload with support for time-series and geospatial data.
GridDB Main Features are:
- IoT Data Model optimization
GridDB's Key Container data model and Time Series functions are purpose built for IoT applications.
- NoSQL Performance
GridDB's "Memory first, Storage second" algorithm automatically allocates HOT data to the memory and SEMI-HOT data to disks.
- SQL Usability
Start right away with the standard SQL, and connect to your favourite applications via JDBC.
GridDB CE v4.5 combines NoSQL and SQL dual interface capabilities, offering high performance and an improved ease of use.
Changes in v4.5 are as follows:
- Added SQL Interface and JDBC Driver
- In addition to the NoSQL interface, it is now possible to access the database using SQL with the JDBC driver.
- SQL92 compliant such as Group By and Join between different tables.
- Added Table Partitioning functionality
- By allocating the data of a huge table in a distributed manner, it is now possible to execute the processors in parallel and speed up access.
- Multiple nodes clustering is changed to a single node setup.
