DingoDB is a real-time Hybrid Serving & Analytical Processing (HSAP) Database. It can execute high-frequency queries and upsert, interactive analysis, multi-dimensional analysis in extremely low latency.

1. Compliant with ANSI SQL
   Based on the popular Apache Calcite SQL engine, DingoDB can parse, optimize and execute standard SQL statements, and is capable to run part of TPC-H and TPC-DS (See TPC) queries. DingoDB is also compliant with JDBC and can be seamlessly integrated with web services, BI tools, etc.
2. Support high frequency write operation
   By using the log-structured key-value storage RocksDB, DingoDB support high frequency write operations like INSERT, UPDATE, DELETE.
3. Support point query and multi-dimensional analysis simultaneously
   DingoDB can store table data in both row-oriented and column-oriented format, providing capability of fast point query and fast multi-dimensional analysis in low latency.
4. Easily integrated with streaming data and other DBMS's
   By providing dedicated APIs for popular streaming data processing engine, e.g. Apache Flink, DingoDB can easily accept data from them, and support more analysis working or web serving that is not applicable to be done in stream. DingoDB can also access databases of many types, using pluggable connectors for each of them.
5. Resilience for deployment and maintenance
   DingoDB stores and processes data in a distributed manner with strong cluster and resource management functionality, which make it easy to expand the capacity.

We recommend IntelliJ IDEA to develop the DingoDB codebase. Minimal requirements for an IDE are:

• Support for Java
• Support for Gradle

The IntelliJ IDE supports Java and Gradle out of the box. Download it at IntelliJ IDEA website.
