 ## Changelog
+### 3.1.??
+- 1232-process-the-full-text-dump
+  - Description: A script was added `/scripts/sde_dump_processing/clean_text_dump.py` which cleans dumps from sinequa. The sinequa dump does not respect normal csv new line formatting, so that a dump of 1.8 million records becomes a csv of 900 million lines. This script can detect the headers and process the dump with the three possible sources TDAMM, SDE, and scripts, in order to create a final, clean csv. It has a simple CLI which allows setting the input and output, the verbosity of the logs, etc. Because the input files can be very large, the script streams them instead of holding them in memory.
