Storage Synchronization and "with" Context

Synchronizing data with long-term storage and achieving optimal performance using Deep Lake.

How Deep Lake Datasets are Synchronized with Long-Term Storage

Using with context when updating Deep Lake datasets is critical for achieving rapid write performance.

BAD PRACTICE - Code without with context

Any standalone update to a Deep Lake dataset is immediately pushed to the dataset's long-term storage location. Due to the high number of write operations, there may be a significant increase in runtime when the data is stored in the cloud. In the example below, an update is pushed to storage for every call to the .append() command.

for i in range(10):
    ds.my_tensor.append(i)

Code using with context

To increase write speeds when using Deep Lake, the with syntax significantly improves performance because it only pushes updates to long-term storage after the code block inside the with statement has been executed, or when the local cache is full. This significantly reduces the number of discreet write operations, thereby increasing the speed by up to 100X.

with ds:
    for i in range(10):
        ds.my_tensor.append(i)
