Talend has started leveraging Apache Spark as part of its big data integration platform. Spark leverages the speedy in-memory execution capability to accelerate data ingestion. Migrating to Apache Spark can provide performance improvements from 5 to 100 times.
Talend promises to make the migration literally as simple as the push of a button with a new refactoring option that can automatically convert data pipelines written for MapReduce to Spark. MapReduce was the previous leader in high-performance data integration. That theoretically requires no changes to the high-level workflows that a user has defined for a cluster.
New projects also benefit from the upgrade, which brings some 100 pre-implemented data ingestion and integration functions that make it possible to pull data into Spark without having to do any programming. According to Talend, the result is an up to tenfold improvement in developer productivity.
There are a number of new Talend features, with the biggest additions being “masking” or also commonly known as Tokenisation. This allows an organization to replace a sensitive file with a structurally similar placeholder that doesn’t reveal any specific details. That’s useful in scenarios where, say, an analyst at a hospital that doesn’t have permission to view patient treatment history wants to check how many medical records there are in a given dataset coming into Spark.
