@Gowthami03B That would be great! 👍
One note here:
> important if we just want to check that a table exists in a namespace. I'd
argue this is the same as calling list_tables and checking if the table exists
in the returned list, and hence isn't as critical to implement as 'CREATE TABLE
IF NOT EXISTS'
I think it would make more sense to do an actual `load_table` instead of
calling `list_tables`, mostly because there is a discussion on the REST spec to
add pagination. Calling the `list_table` would then result in many consecutive
requests to build up the list, which is not very performant. For the
`load_table` we load the metadata, but I think that's okay.
Thanks @syun64 for summarizing the options.
> An alternative is just to ask users to try and catch
TableAlreadyExistsError in their code when calling create_table
I believe this is the most Pythonic way of doing it, but I agree that we
could mirror the SQL `CREATE IF NOT EXISTS`. How about adding this to the
`Catalog(ABC)` itself. This way we don't have to add this logic to each of the
implementations:
```python
catalog = load_catalog('default')
catalog.create_table_if_not_exists('schema.table', schema=...)
```
Thoughts?
