/**
- * The IcebergSource loads/writes tables with format "iceberg". It can load
paths and tables.
+ * Data source for reading and writing Iceberg tables using the "iceberg"
format.
*
- * <p>How paths/tables are loaded when using
spark.read().format("iceberg").load(table)
+ * <p>The `path` parameter provided by Spark is resolved in the following
priority order:
*
- * <p>table = "file:///path/to/table" -> loads a HadoopTable at given path
table = "tablename"
- * -> loads currentCatalog.currentNamespace.tablename table =
"catalog.tablename" -> load
- * "tablename" from the specified catalog. table = "namespace.tablename" ->
load
- * "namespace.tablename" from current catalog table =
"catalog.namespace.tablename" ->
- * "namespace.tablename" from the specified catalog. table =
"namespace1.namespace2.tablename" ->
- * load "namespace1.namespace2.tablename" from current catalog
- *
- * <p>The above list is in order of priority. For example: a matching catalog
will take priority
- * over any namespace resolution.
+ * <ol>
+ * <li>Rewrite key - If `path` is a key in the table cache, load from the
rewrite catalog
Review Comment:
nit: maybe `cache catalog` instead of `rewrite catalog`?
