#parallelStream - Twitter Hashtag

Are you using .parallelStream() in production? If you don’t understand how your Collector behaves under parallelism, you might be aggregating nonsense at scale. 👉 https://t.co/Bis290TZWc #Java #Streams #parallelStream #Concurrency

A bit sad #java decided to go with #parallelStream as a first citizen, in a concurrent application it is actually (almost?) never a good choice cause concurrency and speed comes from elsewhere but it is in all API (#collector) and verbose for nothing

#Stream vs #ParallelStream; * stream() --> sequential stream using a single thread * parallelStream() --> using multi-threads, order of execution of streams cannot be controlled. Leverage the performance. Should not be used when order is crucial. #WeeklyJavaTips #Java

evrn_tan's tweet photo. #Stream vs #ParallelStream;

* stream() --> sequential stream using a single thread
* parallelStream() --> using multi-threads, order of execution of streams cannot be controlled. Leverage the performance. Should not be used when order is crucial.

#deadlock #parallelstream #java #transaction #sql #CaParleDev A cute bug just taught me to avoid using java parallelstream with transactions because deadlocks might occur. Even if parallelstream lets us to take advantage of concurrency, we have to think twice before using it.
