Apache NiFi 1.2.0 发布，数据处理和分发系统

Apache NiFi 1.2.0 发布了，Apache NiFi 是一个易于使用、功能强大而且可靠的数据处理和分发系统。它为数据流设计，支持高度可配置的指示图的数据路由、转换和系统中介逻辑。新版本更新内容包括：

核心架构：

• Now supports running multiple versions of the same components.  Makes upgrades and multi-tenant flows easier to manage as sets the stage for upcoming Apache NiFi Registry work!

• New provenance repository implementation available called 'WriteAheadProvenanceRepository'.  Huge performance increase over the standard implementation and indexes in real-time.

新特性或改进：

• New Record oriented abstraction for reading/writing schema aware event streams from CSV, JSON, AVRO, Grok, and plaintext with easy extension for other formats/schemas

• QueryRecord processor to execute SQL queries over a stream of records powered by Apache Calcite

• ConvertRecord processor to efficiently transform records from a given schema and format into another schema and format

• SplitRecord processor to efficiently split huge record bundles into configurable batch sizes for divide and conquer or protect downstream systems

• Processors to efficiently stream Records into and out of Apache Kafka in a format and schema aware manner and which automatically handle achieving high throughput and full provenance

• Controller Services for plugging into and managing data schemas (Avro Schema Registry, Hortonworks Schema Registry) that integrate nicely into the record readers and writers

• Features/improvements related to Change Data Capture (CDC), including CaptureChangeMySQL which reads from the MySQL binlogs, EnforceOrder, and PutDatabaseRecord processors, as well as a "Rollback on Failure" capability of some Put processors
