This is a golang implementation of the bitcask key-value database. It prioritized high performance and fault-tolerance.
This displays comman usage of the database. The second parameters passed into database are the options.
package main
import (
"bytes"
"log"
"github.com/nireo/bitcask"
)
func main() {
db, err := bitcask.Open("./data", nil)
if err != nil {
log.Fatalf("could not open the database: %s", err)
}
defer db.Close()
key := []byte("hello")
value := []byte("world")
if err := db.Put(key, value); err != nil {
log.Fatalf("could put into database: %s", err)
}
val, err := db.Get(key)
if err != nil {
log.Fatalf("could key from the database: %s", err)
}
if !bytes.Equal(val, value) {
log.Fatalf("the values don't match")
}
}I think that this isn't for every single use case, but it really depends on the situtiation.
- Simple Code
- Very high throughput
- Predictable performance
- High memory usage
- Can take more disk space since metadata is also written to disk
