WebJan 7, 2024 · Flink is a new generation of computing engines that can support both stream and batch processing of data. It reads data from a third-party storage engine, processes them, and then writes them to another storage engine. A Flink Connector works like a connector, connecting the Flink computing engine to an external storage system. WebSink that emits its input elements to FileSystem files within buckets. This is integrated with the checkpointing mechanism to provide exactly once semantics. When creating the sink a basePath must be specified. The base directory contains one directory for every bucket.
