Data Pipeline 3.0 Now Available

We’re pleased to announce the release of version 3.0 of our Data Pipeline engine.

This release includes the new Sliding Window Aggregations feature to perform continuous SQL group-by operations on streaming data.

We’ve improved the performance of the XPath based readers (JsonReader, XmlReader, and JavaBeanReader), included new conveniences to reduce your code size, and added several new transformers and filters.

We’re also now offering a free 30-day trial for you to take the premium and enterprise features out for a test drive.

  • BUGFIX: record count is no longer off by 1 in some cases

Data Pipeline 2.2.6 Now Available

  • performance improvements in CSV and fixed width handling
  • untyped expression evaluation is now based on the value’s type, instead of the field’s declared type
