If memory is insufficient, the library Parsers cannot process very large inputs in a single block. Instead, you can use a Streamer to break the input into segments and parse them. The DTCC-NSCC library provides a set of sample Streamers.

The input that you pass to the Streamer must terminate with the following string, signaling the end of the data:

In Streamer mode, the DTCC-NSCC library Parsers do not validate the uniqueness of contract IDs.

To use the sample Streamers, import the sample Script with the Streamers into the Developer tool, then copy the Scripts to a Data Processor transformation with a DTCC-NTCC Library object.
