createSession

createSession(
    root: CID,
    options?: CreateSessionOptions<
        GetOfflineOptions & (ProviderOptions & GetBlockProgressEvents),
    >,
): SessionBlockstore
A blockstore session only fetches blocks from a subset of network peers to reduce network traffic and improve performance.

The initial set of peers can be specified, alternatively a findProviders routing query will occur to populate the set instead.
Parameters
- root: CID
- Optionaloptions: CreateSessionOptions<
  GetOfflineOptions & (ProviderOptions & GetBlockProgressEvents),
  >
Returns SessionBlockstore
- Defined in packages/interface/src/blocks.ts:82

delete

delete(
key: CID,
options?: AbortOptions & ProgressOptions<DeleteBlockProgressEvents>,
): Await<void>
Remove the record for the passed key
Parameters
- key: CID
- Optionaloptions: AbortOptions & ProgressOptions<DeleteBlockProgressEvents>
Returns Await<void>
Example
```
await store.delete(new Key('awesome'))
console.log('deleted awesome content :(')
```

Parameters
- source: AwaitIterable<CID<unknown, number, number, Version>>
