Meanwhile, AWS s data lake – Elastic Map Reduce – can handle SQL queries via SQL Workbench or Presto SQL. Azure supports SQL queries in its data lakes (HD Insight or Azure Databricks) while GCP uses a combination of Bigtable, Dataflow and Bigquery.
But these implementations are not able to handle the number of SQL queries supported by traditional data warehouses, some of which can scale to thousands of concurrent users.
Latency and concurrency an issue
Pal told the Gartner Data & Analytics Summit: Data lakes are actually not being used for BI workloads, especially in large organizations that need high concurrency, as well as low latency.
