CTU relational datasets (redelex)

71 databases from the CTU Prague Relational Learning Repository in RelBench format, ported via redelex. Labels are redelex's task definitions served as-is (kind: external); *-original tasks use a fixed random 80/10/10 entity split, *-temporal tasks split by time. The dataset viewer lists every database and task.

<dataset>/
  manifest.yaml                 # tables, primary keys, foreign-key graph, val/test timestamps
  schema.svg                    # ER diagram
  db/*.parquet                  # relational tables
  tasks/<task>/manifest.yaml    # task spec
  tasks/<task>/{train,val,test}.parquet

import relbench
ds = relbench.load_dataset("stanford-star/redelex/ctu-financial")
task = relbench.load_task("stanford-star/redelex/ctu-financial", "<task>")
