It can be deployed as a sidecar. +First, `Arana` is a Cloud Native Database Proxy. It provides transparent data access capabilities, when using `arana`, +user doesn't need to care about the `sharding` details of database, they can use it just like a single `MySQL` database. +`Arana` also provide abilities of `Multi Tenant`, `Distributed transaction`, `Shadow database`, `SQL Audit`, `Data encrypt / decrypt` +and so on. Through simple config, user can use these abilities provided by `arana` directly. + +Second, `Arana` can also be deployed as a Database mesh sidecar. As a Database mesh sidecar, arana switches data access from +client mode to proxy mode, which greatly optimizes the startup speed of applications. It provides the ability to manage database +traffic, it takes up very little container resources, doesn't affect the performance of application services in the container， but +provides all the capabilities of proxy. ## Architecture + + ## Features -| feature | complete | -| -- | -- | -| single db proxy | √ | -| read write splitting | × | -| tracing | × | -| metrics | × | -| sql audit | × | -| sharding | × | -| multi tenant | × | +| **Feature** | **Complete** | +|:-----------------------:|:------------:| +| Single DB Proxy | √ | +| Read Write Splitting | √ | +| Sharding | √ | +| Multi Tenant | √ | +| Distributed Primary Key | WIP | +| Distributed Transaction | WIP | +| Shadow Table | WIP | +| Database Mesh | WIP | +| Tracing / Metrics | WIP | +| SQL Audit | Roadmap | +| Data encrypt / decrypt | Roadmap | ## Getting started +Please reference this link [Getting Started](https://github.com/arana-db/arana/discussions/172) + ``` arana start -c ${configFilePath} ``` ### Prerequisites -+ MySQL server 5.7+ ++ Go 1.18+ ++ MySQL Server 5.7+ ## Design and implementation ## Roadmap ## Built With -- [tidb](https://github.com/pingcap/tidb) - The sql parser used + +- [TiDB](https://github.com/pingcap/tidb) - The SQL parser used ## Contact +Arana Chinese Community Meeting Time: **Every Saturday At 9:00PM GMT+8** + + + ## Contributing +Thanks for your help improving the project!
