Highlights:

  • extdedup & extsort now support two modes - LINE mode and CSV mode. Previously, both commands only sorted on a line-by-line basis (LINE mode).
    With the addition of CSV mode, you can now deduplicate or sort CSV files on a column-by-column basis, with the powerful --select option to specify which columns to deduplicate or sort on.
    This is especially useful for large CSV files with many columns, where you only want to deduplicate or sort on a subset of columns. And since both commands use disk-backed algorithms (an on-disk hash table for extdedup, and an external merge sort for extsort) - they can handle files larger than memory.
  • sqlp now has a --cache-schema option that caches the inferred schema of the input CSV file, which can significantly speed up subsequent queries on the same file, as the initial schema inferencing step is skipped.
  • fetch and fetchpost have been updated to use the jaq crate instead of the jql crate. This change was made to improve performance and to make the commands consistent with the json command which also uses jaq. Furthermore, jaq is a clone of jq - a widely used JSON parsing tool, so it should be more familiar to users.
  • stats is a tad faster as we keep squeezing more performance from this central command.
