## keev
keev is a simple key-value store built on top of hash tables using Go. Clients communicate with the server using gRPC and Google Protocol Buffers (protobufs). Data persist to disk and saving occurs every 5 minutes.

Database current accepts the following commands:
- SET key value (valid if key is not present)
- UPDATE key value (valid if key is present)
- HAS key
- UNSET key
- GET key
- COUNT
- SHOW KEYS
- SHOW DATA
- SHOW NAMESPACES
- USE namespace
Restrictions:
* Both `key` and `value` cannot contain spaces.
* `key` cannot contain dots.
* Only alphanumeric characters are allowed for `namespace`
## Usage
1. Generate certificates for RPC: `go run generate_cert.go --host=localhost`
2. Change `JWTSigningToken` in `common/jwt.go`.
3. Define a list of users in `data/users.json`.
Sample:
```json
[
{
"username": "admin",
"password": "admin123",
"perms": ["ADMIN"]
},
{
"username": "user",
"password": "user123",
"perms": []
}
]
```
Server: `./server`
Client: `./client --username="user" --password="user123"`
## Program

## Future work?
- [ ] Permissions for users
- [ ] Tests
- [ ] Logs
- [ ] Own SQL-like syntax with lexer and parser
- [ ] Transactions
- [ ] Support for various types: numbers, etc.
- [ ] Drivers for other languages
- [ ] Scaling/fault-tolerant system using Raft/Paxos
