Merge Multiple Spark Streams Into A Delta Table with working code This blog will discuss how to read from multiple Spark Streams and merge/upsert data into a single Delta Table. We will also optimize/cluster data of the delta table. Overall, the process works in the following manner: Read data from a streaming source Use this special function ***foreachBatch. ***Using this we will call any user-defined function responsible for all the processing.
Using Spark Streaming to merge/upsert data into a Delta Lake with working code This blog will discuss how to read from a Spark Streaming and merge/upsert data into a Delta Lake. We will also optimize/cluster data of the delta table. In the end, we will show how to start a streaming pipeline with the previous target table as the source. Overall, the process works in the following manner, we read data from a streaming source and use this special function ***foreachBatch.
