Data lakes and datawarehouses are two of the most important data storage and management technologies in a modern data architecture. Data lakes store all of an organization’s data, regardless of its format or structure. Delta Lake doesn’t have a specific concept for incremental queries.
Unlocking the true value of data often gets impeded by siloed information. Traditional datamanagement—wherein each business unit ingests raw data in separate data lakes or warehouses—hinders visibility and cross-functional analysis.
Organizations are dealing with exponentially increasing data that ranges broadly from customer-generated information, financial transactions, edge-generated data and even operational IT server logs. A combination of complex data lake and datawarehouse capabilities are required to leverage this data.
