[DISCUSS] Name of Expression API and DataSet abstraction

[Aljoscha Krettek <al...@apache.org>]

Hi Folks,
as mentioned in the title, we need a good name for this. Right now the
API is called Expression API, the package is flink-expressions and the
thing on which you call operations (equivalent to DataSet or
DataStream) is called ExpressionOperation. Especially the last one is
extremely ugly.

Do you have any ideas how we should name those things? @Fabian
mentioned Relation API and Relation, as name for the thing on which
you work.

Cheers,
Aljoscha

I like Relation and Relation API more than Table API.
Rel is quite cryptic though :)

Re: [DISCUSS] Name of Expression API and DataSet abstraction

[Fabian Hueske <fh...@gmail.com>]

I agree with Aljoscha on this. DataTable does not make a lot of sense to
me... (except for going nicely with DataSet and DataStream).

Re: [DISCUSS] Name of Expression API and DataSet abstraction

[Alexander Alexandrov <al...@gmail.com>]

+1 for DataTable as core abstraction name and "flink-table" or something
similar as the package name.

Re: [DISCUSS] Name of Expression API and DataSet abstraction

[Henry Saputra <he...@gmail.com>]

When consensus not happening we will go with VOTE. I think we have 2
candidates of names which are table and relation.

Re: [DISCUSS] Name of Expression API and DataSet abstraction

[Paris Carbone <pa...@kth.se>]

Both names look ok but if I had to choose I would go for the Relation API.
It defines a new DSL in contrast to data types (ie DataSet, DataStream) so it doesn’t have to follow the same convention.
Plus, it is a single word with sufficient meaning.

I'm in favor of DataTable for the DataSet abstraction

For
consistency, the package name should then be flink-table. At
first
sight, the name seems kind of plain but I think it is quite
intuitive
because the API enables you to work in a SQL like fashion.

I think this is a very good suggestion. :-)

Re: [DISCUSS] Name of Expression API and DataSet abstraction

[Henry Saputra <he...@gmail.com>]

OK, as recommended by Fabian, I explain why I like Relational better =)

The concept of Relational suggest the concept of querying data based
on the relationship of different sources and the predicates/ filters
attached to them.

Or we could go more like keyword name such as "REMOQ" which stands for
Relational Model Query =P
This way is in the same spirit as Gelly as the name of the new graph modiule.

Re: [DISCUSS] Name of Expression API and DataSet abstraction

[Henry Saputra <he...@gmail.com>]

I like the Relation or Relational. So maybe we could use DataRelation
as the abstraction?

I am also more in favor of Rel and Relation, but DataTable nicely follows
the terms DataSet and DataStream.

I think this is a very good suggestion. :-)

Re: [DISCUSS] Name of Expression API and DataSet abstraction

[Maximilian Michels <mx...@apache.org>]

Hi Aljoscha,

Thanks for starting the discussion. We should definitely not keep
flink-expressions.

I'm in favor of DataTable for the DataSet abstraction equivalent. For
consistency, the package name should then be flink-table. At first
sight, the name seems kind of plain but I think it is quite intuitive
because the API enables you to work in a SQL like fashion.

Best,
Max
