LSM-Tree based storage engine used by FOIVER system.

}ORIGINIUM supports concurrent ACID transactions with Serializable Snapshot Isolation (SSI) guarantees.
- Read-only transaction
err := db.View(func(txn *originium.Txn) error {
// ...
res, ok := txn.Get("hello")
if !ok {
// key not found
}
// ...
return nil
})- Read-write transaction
err := db.Update(func(txn *originium.Txn) error {
// ...
if err := txn.Set("hello", []byte("originium")); err != nil {
return err
}
// ...
return nil
})- Manually
// start a read-write transaction manually
txn := db.Begin(true)
defer txn.Discard()
// ...
if err := txn.Delete("hello"); err != nil {
return err
}
// ...
if err := txn.Commit(); err != nil {
return err
