> ... currently only support a very limited set of Spark expressions as call
arguments.
Hi, @RussellSpitzer, before finding the final solution to support generic
expressions as call args, could you please list the supported expressions now?
The examples in documents still not work now (iceberg master branch with
spark 3.1).
```
E, statement: CALL iceberg.system.expire_snapshots(table =>
'cdc_wenjuan.member', older_than => now(), retain_last => 1), time taken: 0.004
seconds
Error: Error operating EXECUTE_STATEMENT:
org.apache.spark.sql.catalyst.parser.extensions.IcebergParseException:
mismatched input '(' expecting STRING(line 1, pos 85)
== SQL ==
CALL iceberg.system.expire_snapshots(table => 'cdc_wenjuan.member',
older_than => now(), retain_last => 1)
