Their latest paper [0] refers to Naiad(timely dataflow) a few times, e.g.: "Inspired by ingress/egress nodes in Naiad [34], nested streams can be processed by nested dataflow graphs, which iteratively process chunks of data sourced from a larger stream with support for carrying state across iterations."

There seems to be good progress on a paper on DataFusion. The draft contains some preliminary benchmark results, comparing it to DuckDB.

There's also some really interesting stuff going on in music informatics, audio and signal processing, especially where everything comes together - accompanying human players:

Possibly Bedrock fits your needs: https://bedrockdb.com

"Bedrock [..] is a networking and distributed transaction layer built atop SQLite"

"... That query can be any SQLite-compatible query – including schema changes, foreign key constraints, partial indexes, native JSON expressions, or any of the tremendous amount of functionality SQLite offers."

IMO it would be good to have 'Show HN:' in the title to see that the [owner?] of this site submitted this post.

For ARM thumb2 style you need a third instruction between the two:

  IT EQ

The 'IT' is for 'if then'. There could also be more 'then's and 'else's for the conditional execution of muliple instructions:

  ITTE LT

(If then then else) The following instructions could for example be:

  ADDEQ ...
  STREQ ...
  BNE ... (Branch - not equal because of the else)
