There is a lot of understandable confusion about the difference between sulfa drugs, sulfites, sulfates and sulfur. Many people are allergic to sulfa drugs and sulfites and thus assume that they have to avoid sulfates and sulfur, also.I will explain the difference between these four substances in this article.llergies to sulfa containing drugs are not unusual. Sulfa drugs actually contain a molecule called sulfonamide. Sulfonamides contain Sulfur, Oxygen, Nitrogen, and Hydrogen. The sulfonamide drugs were the first antimicrobial drugs (antibiotics) These molecules plug up the bacteriaâs ability to reproduce.
[SPARK-3466] Limit size of results that a driver collects for each action #3003. Right now, operations like collect() and take() can crash the driver with an OOM if they bring back too many data. This PR will introduce spark.driver.maxResultSize, after setting it, the driver will abort a job if its result is bigger than it. By default, it's 1g (for backward compatibility for most the cases). In local mode, the driver and executor share the same JVM, the default setting can not protect JVM from OOM. cc @mateiz.
SPARK 2014, in contrast, uses Ada 2012's built-in aspect syntax to express contracts, bringing them into the core of the language [2]. The main tool for SPARK 2014 (GNATprove) is based on the GNAT/GCC infrastructure, and re-uses almost the entirety of the GNAT Ada 2012 front-end.PARK 2014 is a complete re-design of the language and supporting verification tools. The SPARK language consists of a well-defined subset of the Ada language that uses contracts to describe the specification of components in a form that is suitable for both static and dynamic verification.
