Connecting

A catalog is the thing that knows where tables are. Credentials come from the environment, never from arguments.

icebergr_catalog(): Connect to an Iceberg catalog
icebergr_list_namespaces(): List namespaces in a catalog
icebergr_list_tables(): List tables in a namespace
icebergr_create_namespace(): Create a namespace

Table handles

A handle is bound to one snapshot, which is what makes two scans off it agree. icebergr_reload() is how you opt in to newer commits.

icebergr_table(): Open an Iceberg table
icebergr_table_exists(): Whether a table exists in a catalog
icebergr_reload(): Re-read a table's metadata from its catalog

Reading

icebergr_scan() pushes the filter and the column list down into iceberg-rust; icebergr_scan_plan() shows what survived before any data file is opened.

icebergr_scan(): Scan an Iceberg table
icebergr_scan_plan(): Inspect the file plan for a scan
icebergr_collect() as.data.frame(<icebergr_scan>) as.data.frame(<icebergr_table>): Materialise a scan or a table

Metadata

icebergr_schema(): The schema of an Iceberg table
icebergr_partitions(): The partition specification of an Iceberg table
icebergr_properties(): The properties of an Iceberg table
icebergr_snapshots(): Snapshot history of an Iceberg table

Writing

Appends, table and namespace creation, and registering a table another engine wrote. What this version will not write, it refuses before anything reaches the warehouse.

icebergr_append(): Append rows to an Iceberg table
icebergr_create_table(): Create an Iceberg table
icebergr_register_table(): Register an existing table with a catalog

Knowing the boundary
