Features

Batch writing

Support BatchedStorage interface.

It allows to cache Put operations and execute them in one batch. In general case it may increase write throughput.

Batch implements Writer interface.

Example:

batchWriter := storage.Batch()

batchWriter.Put([]byte("key1"),[]byte("value1")
batchWriter.Put([]byte("key2"),[]byte("value2")
//...
batchWriter.Put([]byte("keyN"),[]byte("valueN")

// flush/write batch to storage
batchWriter.Close()
