Sort keys (and partition column) for every released table

The ORDER BY that makes an export deterministic must be a unique total order: partition column first, then the clustering sort, then the primary key as the tiebreak. A released table missing from this registry — and without a primary key in core_relationships() — makes export_release_parquet() refuse to write, rather than write non-deterministically.

Usage

release_sort_keys(
  core_sort = c("grid_key NULLS LAST", "depth_min_m NULLS LAST", "measurement_type",
    "datetime")
)

Arguments

core_sort

clustering sort for the long observation tables.

Value

Named list: table -> list(partition_by = <col or NULL>, order_by = <chr>).
