Maxwell Guo commented on CASSANDRA-18920:
-----------------------------------------
yeah, we know that sstabledump already has a option -l to output the partition
in json, the difference between original json output and your jsonl is on
"removes whitespace, including newlines, to make the format compact." but the
original json is still a json format. So I prefer to add arguments behind -l
which like -k
[here|https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/tools/SSTableExport.java#L84]
to show wether is jsonl or original json. [~brandon.williams]

> Add jsonl support to sstabledump
> --------------------------------
>
> Key: CASSANDRA-18920
> URL: https://issues.apache.org/jira/browse/CASSANDRA-18920
> Project: Cassandra
> Issue Type: New Feature
> Components: Legacy/Tools
> Reporter: Geoff Lay
> Assignee: Geoff Lay
> Priority: Low
> Fix For: 5.x
>
>
> Add a new option to sstabledump to allow the generation of jsonl format.
> The -l option for sstabledump does not produce valid jsonl.
> [https://jsonlines.org/validator/]
> Valid jsonl removes whitespace, including newlines, to make the format
> compact.
> By adding an option to generate valid jsonl, jsonl can be generated that is
> smaller.
> Smaller output is better for execution time, storage, and transport.
> jsonl also allows the splitting of a file for processing at a known good line
> for processing without parsing the file, as each row is a line.
