What is a key difference between a data lake and a data warehouse in terms of data storage?

Data lakes can store data in a wider range of formats, including structured, semi-structured, and unstructured data, while data warehouses are typically limited to structured data Signup and view all the answers

Which statement best describes the relationship between a data lake and a data warehouse?

What is a key advantage of data lakes over data warehouses in terms of data storage capacity?

Data lakes can store data in the range of Petabytes (PB), Exabytes (EB), or even higher, while data warehouses might start to experience performance issues at the Petabyte range Signup and view all the answers

What is the main difference between strongly consistent data stores and eventually consistent data stores?

Strongly consistent data stores update all data copies before allowing other operations, while eventually consistent data stores gradually update data copies over time. Signup and view all the answers

Why do queries running on strongly consistent data stores tend to be slower compared to eventually consistent data stores?

Strongly consistent data stores involve updating all data copies before processing queries. Signup and view all the answers

In a storage system that supports multiple levels of consistency, what would happen if a user performs an operation before all data copies are updated?

The operation will wait until all data copies are updated in the storage system. Signup and view all the answers
