Question

Where does a KV Store lookup live?

1) In memory
2) On disk
3) In cache
4) In the cloud

Answer 1

A KV Store lookup typically lives in memory, but it can also be stored on disk for durability. Cache is used to enhance performance.

Step-by-step explanation:

The KV Store lookup typically lives in memory to ensure fast and efficient data retrieval. The data in a KV Store is stored in key-value pairs, where each value is associated with a unique key. When a lookup is performed, the KV Store searches for the corresponding value based on the provided key.

Although the KV Store data primarily resides in memory, it can also be persisted on disk for durability and fault tolerance. Storing data on disk allows the KV Store to recover data in case of system failures or restarts.

While the KV Store lookup depends on memory and disk for storage, it can also utilize cache to improve performance. Cache is a temporary storage that holds frequently accessed data, allowing for quicker retrieval.
