Presto Notebooks are Generally Available¶
PRES-1996: Presto Notebooks are generally available, with these changes:
QDS has implemented a native Presto Interpreter; this shows progress as a percentage in the Notebook UI.
Concurrency is supported. You can specify maximum concurrency using
zeppelin.presto.maxConcurrencywhen you create the interpreter; the default is 10.
This feature will be enabled for use in the next few days.
Presto 0.208 is Supported¶
- PRES-2026: Makes planning-time improvements to speed up plan generation for queries that have complex predicates or operate on tables with many partitions.
- PRES-2150: Resolves an issue that caused queries using
memory counters to fail intermittently with the error
Future should be done.
- PRES-2168: Fixes a Dynamic Filtering bug related to concurrency.
- PRES-2232: Resolves a problem that caused failures in queries using the
