Tenzir Node v4.29: Nested Printing

Tenzir Node v4.29 introduces new functions for printing values as strings, complementing v4.28's parsing functions.

Printing Values

With this release, we've added a bunch of new functions for printing values as strings:

• print_json prints any value as its JSON representation.
• print_yaml prints any value as its YAML representation.
• print_csv, print_ssv, and print_tsv to print records as comma-, space- and tab-separated strings respectively.
• print_kv prints any value as a sequence of key-value pairs.

The new print_* functions behave similar to the write_* operators, except that they work on values within events instead of streams of events.

In addition, we also added a new operator, write_kv. It is the dual for our read_kv operator and enables you to write events as key-value pairs.

Pipelines May Require Updating

Along with these new functions, we decided to streamline arguments for a lot of reading & writing operators as well as the parsing function. Their separator arguments are now all named arguments and the suffix *_sep has been replaced with a proper *_separator. Additionally, the unflatten option is now called unflatten_separator. For more details, see the changelog.

Timely Functions

We introduced new functions ranging from years(number) to nanoseconds(number), which allow you to convert any number to a duration. Their counterparts, such as count_years(duration), convert a duration back into plain count of the respective unit.

Fixes, Improvements & Other Small Changes

This release also contains a number of small fixes and improvements, which you can find in the changelog.
