Finatra

Added

• inject-app: Add Java-friendly main to EmbeddedApp. 4b40075d

• finatra-kafka: Expose timeout duration in KafkaProducerConfig dest(). c5340a97

Changed

• finatra-validation|jackson: (BREAKING API CHANGE) Introduced new case class validation library inspired by JSR-380 specification. The new library can be used as its own to validate field and method annotations for a case class. The library is also automatically integrated with Finatra’s custom CaseClassDeserializer to efficiently apply per field and method validations as request parsing is performed. However, Users can easily turn off validation during request parsing with the setting noValidation in their server configurations. For more information, please checkout Finatra User’s Guide. d874b1a9

Util

New Features

• util-core: When looking to add idempotent close behavior, users should mix in CloseOnce to classes which already extend (or implement) Closable, as mixing in ClosableOnce leads to compiler errors. ClosableOnce.of can still be used to create a ClosableOnce proxy of an already instantiated Closable. Classes which do not extend Closable can still mix in ClosableOnce. 43671464

Breaking API Changes

• util-hashing: Rename c.t.hashing.KetamaNode => HashNode, c.t.hashing.KetamaDistributor => ConsistentHashingDistributor. f595ed97
