Rest api - MetaModel-as-a-Service - draft application
Hi all,
This is my attempt at building a 'MetaModel-as-a-Service' webapp. Although
it is not yet as great as I imagine it should be before we release it, I do
think there's a considerable amount of work here to go with, and that might
trigger others who want to help with the finishing touches.
This webapp allows the user to define data sources in a number of groups
(in the code I used the word 'tenant' because I imagine usually each group
would be a tenant of the application). The data source can then be explored,
queried and updated using RESTful endpoints. For example:
* `PUT /t1` would register a new data source with name 't1'.
* `PUT /t1/ds` would register a new data source with name 'ds'.
* `GET /t1/ds` would show information about 'ds', including it's schema
names.
* `GET /t1/ds/s/public` would show information about the schema 'public'.
* `GET /t1/ds/s/public/t/customers` would show information about the table
'customers' in schema 'public'.
* `POST /t1/ds/s/public/t/customers` would insert data into the
'customers' table.
* `GET /t1/ds/q?sql=SELECT+name+FROM+customers` would fire the given query
to the data source.
(see the controllers package for all endpoints).
Here's what is missing (as far as I can think of) before I think it is
_really_ releasable:
- No formal interface documentation yet (I think we should add a swagger
file).
- No persistence of tenant or datasource information (I imagine we can
have many ways of implementing this - the simplest would simply be a
folder/file based persistence of tenant folders and data source folders / JSON
files).
- So far only a simple datasource definition reader for POJO data (but
others should be very easy to add - I suggest adopting the `MetaModel-spring`
module's approach to this).
Would love a review and discussion, and would invite anyone else to further
contribute to making this releasable.
