Summary

  • Pin TZ=UTC in the ClickHouse, asap-planner, and query-engine docker-compose configs and remote-launch commands so naive datetime-string time literals in SQL queries parse identically everywhere (previously could silently disagree by the shell's local UTC offset vs. ClickHouse's UTC default).
  • Pass optional sketch_parameters through from experiment config into the generated SQL planner input YAML.
  • Rsync init_sql_file to the remote node before executing it, instead of assuming it's already present there.

Naive datetime-string time literals in SQL queries were parsing
inconsistently between ClickHouse (defaults to UTC) and asap-planner /
query_engine_rust (local shell TZ), silently disagreeing by the shell's
UTC offset. Also passes optional sketch_parameters through to the
generated SQL planner input, and rsyncs init_sql_file to the remote
node instead of assuming it's already there.
