Export a DuckLake table as Iceberg format (EXPERIMENTAL)

Exports a DuckLake table to Iceberg format for compatibility with other data lakehouse engines (Spark, Trino, Presto, etc.).

Note: This is experimental. DuckLake 0.3+ supports Iceberg interoperability via COPY FROM DATABASE ducklake TO iceberg_catalog. This function attempts to use internal DuckLake Iceberg functions which may not be available.

Usage

db_export_iceberg(
  schema = "main",
  table,
  path = NULL,
  catalog_type = c("hadoop", "hive", "rest")
)

Arguments

schema

Schema name (default "main")

table

Table name

path

Output path for Iceberg metadata. If NULL, uses the table's existing data path with an iceberg/ subdirectory.

catalog_type

Type of Iceberg catalog to generate: "hadoop" (default), "hive", or "rest".

Value

Invisibly returns the output path
