MarioDB

MarioDB is a levelDB-based DBMS (Database Management System).

MarioDB has implemented basic stand-alone function based on C/S, and is considering joining the distributed service.
As a k/v database, marioDB supports unstructured data.

Client

Currently MarioDB has only one test client implemented with go (https://github.com/Diode222/MarioDB_Client),
it's not a real dababase client, just for testing purposes. But when I finish all the design of MarioDB,
I will complete the implementation of the client.

Usage

MarioDB supports both local startup and docker startup with some custom parameters.

1. Local startup

Requires:

(1) golang 1.13 (Should work if golang>=1.11 or higher.)
(2) GO111MODULE=on (go module environment)

Steps:

(1) go get github.com/Diode222/MarioDB
(2) go build main.go (In the path of MarioDB)
(3) ./main -h (This command can see the specific meanings of all parameters, printed as follows)

Usage:

-ip           string    IP                              (Default: 127.0.0.1)
-port         string    Port                            (Default: 45555)
-dbPath       string    Database's data path            (Default: /home/diode)
-maxClient    string    Max count of connected clients  (Default: 100)
-dbLRUMax     string    Max count of db caches in LRU   (Default: 100)

Example: ./main.go -ip 127.0.0.1 -port 50000 -dbPath /home/diode/levelDB_database_root/ -maxClient 20 -dbLRUMax 20

2. Docker startup

Requires:

Docker

Steps:

(1) sudo docker build -t mariodb:latest .
(2) docker run -dit --network host -v /home/diode/dbdatapath:/root/data mariodb -ip 127.0.0.1 -port 45555 -dbPath /root/data -maxClient 20 -dbLRUMax 20

TODO

1. Implement a logging system to increase availability.
2. Load balancing, read/write separation.
3. Basic distributed services based on log system and raft.
4. Cluster deployment of distributed services.
