Function batchGet

batchGet(requestItems: Record<string, Omit<KeysAndAttributes, "Keys"> & { Keys: undefined | Record<string, any>[] }>[], options?: Partial<BatchGetCommandInput>): Promise<BatchGetCommandOutput>

// These two are equivalent
df.batchGet([
  bi.get('movies', { actor: 'Tom Hanks', movie: 'Toy Story' }),
  bi.get('movies', { actor: 'Tom Hanks', movie: 'Forrest Gump' }),
])

df.batchGet([
  bi.get('movies', [
    { actor: 'Tom Hanks', movie: 'Toy Story' },
    { actor: 'Tom Hanks', movie: 'Forrest Gump' },
  ])
])
```
