Hi Gimantha, I think following the conventions will be more intuitive to the users, and we should have a proper reason to not follow. And the post request is generally needs to be sent to create the object and the back end is going to decide where to create the tables resource, therefore it should be POST to '/analytics/tables' and message body should be having the table name. If you want to use /analytics/{tableName}, then you should use PUT rather POST [1]. But IMO POST is the most suitable operation for this context.
And through out the below given URL patterns, in order to fetch the records from a table, you have used '/analytics/records/{tableName}' url pattern where 'records' is in the middle and it is not the correct data hierarchy and again I feel it's not the convention. Basically tables contains records and not records contains tables. Therefore if we use POST to '/analytics/tables' for create table, then you can use simply user 'analytics/{tableName}' to GET/POST for the tables, IMHO the records is just an additional segment which is not needed to be here.
