  1. What does Data Pipeline do?
    Data Pipeline makes it easy to add data conversion, processing, and transformation to Java applications.

Development

  1. How do I get started?
    Our Getting Started Guide and Examples will have you up and running quickly.
  2. Why does my program stall?
    Data Pipeline may stall if DataReader.read() is called before DataReader.open().
  3. Why do I get out of memory exception?
    Java's default, maximum memory size of 64 MB may not be adequate for your application.  Try using the -Xmx Java option to set a higher maximum.
  4. Which version of Java does Data Pipeline support?
  5. Are there any debugging or logging functions?
    Yes. DebugReader can be layered onto another DataReader to log everything it reads.
  6. What libraries are required?
    Data Pipeline is distributed with all the necessary libraries (except for JDBC drivers) under the distributions lib folder.
  7. How do I cache data?
    Data can be cached in a RecordList in one of two ways:
    1. Automatically, by writing to a MemoryWriter then calling getRecordList(). See the write to memory example.
    2. Manually, by creating a RecordList and adding Records to it. See the read from memory example.
  8. Does Data Pipeline support searching?
    Yes. RecordLists can be searched by calling findAll(), findFirst(), or findLast() . Searches can also be performed by filtering incoming data.
  9. Does Data Pipeline support filtering?
    Yes. FilteringReader provides a means of selecting records either programmatically or using the run-time expression language. See the filter records example.
  10. How do I load MS Excel files that use VLookup.
    Simply reading an MS Excel file with the evaluateExpressions property set to true (by default) will cause VLookups to be evaluated. See the read from an Excel file example.
