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."

"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."

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)
