3. 01, Jan 21. This was a brief introduction of Hive, Spark, Impala and Presto. Someone may have already written the code that you need for your project. Presto has a limitation on the maximum amount of memory that each task in a query can store, so if a query requires a large amount of memory, the query simply fails. Some popular ones include: The 5 biggest differences between Presto and Hive are: Customer Story Such error handling logic (or a lack thereof) is acceptable for interactive queries; however, for daily/weekly reports that must run reliably, it is ill-suited. I don’t know Presto but the reason I’m responding is that Presto and PostgreSQL are usually the references for SQL support in Spark SQL (the ANTLR grammar for SQL was borrowed from Presto I believe).

You may find that you can retrace your steps, resolve the problem, and pick up where you left off. Today, companies working with big data often have strong preferences between Presto and Hive. People without coding experience can use Xplenty to extract, transform, and load data with minimal training. Many of our customers issue thousands of Hive queries to our service on a daily basis. Druid and Presto can be categorized as "Big Data" tools. Hive will not fail, though. , so you can always look up commands when you forget them.
