Question

Some developers think of Cloud Bigtable as a persistent hashtable. What does that mean?

a) Each item in the database consists of exactly the same fields, and can be looked up based on a variety of keys.
b) Each item in the database can be sparsely populated, and is looked up with a single key.

Answer 1

Cloud Bigtable is like a persistent hashtable that allows for storing and retrieving data using key-value pairs efficiently. It supports sparsely populated items.

Step-by-step explanation:

Cloud Bigtable can be thought of as a persistent hashtable because it provides a way to store and retrieve data using a key-value pair structure, similar to a hashtable.

Each item in Cloud Bigtable is stored with a unique key, and the data is indexed and organized based on these keys, allowing for efficient lookup and retrieval.

Furthermore, Cloud Bigtable allows for sparsely populated items, meaning that not all fields within an item need to be populated. This provides flexibility in storing data and reduces storage space requirements for sparse data.
