Now that we have seen some basic usage of how to extract data using Sqoop and Spark, I want to highlight some of the key advantages and disadvantages of using Spark in such use cases. Final decision to choose between Hadoop vs Spark depends on the basic parameter – requirement. NumPartitions also defines the maximum number of “concurrent” JDBC connections made to the databases. Thus have fast performance. Dataframes are an extension to RDDs which imposes a schema to the distributed collection of data. Rust vs Go 2. This could be used for cloud data warehouse migration. Hadoop got its start as a Yahoo project in 2006, becoming a top-level Apache open-source project later on. Sqoop: Apache Sqoop reduces the processing loads and excessive storage by transferring them to the other systems. LowerBound and UpperBound define the min and max range of primary key, which is then used in conjunction with numPartitions that lets Spark parallelize the data extraction by dividing the range into multiple tasks. If the table does not have a primary key, users specify a column on which Sqoop can split the ingestion tasks. Sqoop is heavily used in moving data from an existing RDBMS to Hadoop or vice versa and Kafka is a distributed messaging system which can be used as a pub/sub model for data ingest, including streaming. Apache Spark is much more advanced cluster computing engine than Hadoop’s MapReduce, since it can handle any type of requirement i.e. When persisting data to filesystem or relation database, it is also important to use a coalesce or repartition function to avoid writing small files to the file system OR reduce the number of JDBC connections used to write to target a database. It uses in-memory processing for processing Big Data which makes it highly faster.
