At this moment relu_layer op doesn't allow threshold configuration, and legacy RELU op allows that.
We should add configuration option to relu_layer.

This will be a breaking change so needs to be done with a major release.

Currently OperationDetail and OperationField are inner classes within OperationServiceV2. These should be in their own outer classes for ease of serialisation and consistency.

Given, two tables, if they are joined, and then a filter is applied, the filter is actually being ignored:

import ibis

ibis.options.interactive = True

connection = ibis.sqlite.connect('data/geography.db')
countries = connection.table('countries')
gdp = connection.table('gdp')

expr = (countries.inner_join(gdp,
                             predicates=countries['iso_alpha3']

Currently, it's ignored silently. We need to consider some RDBMS doesn't support setting a column comment in CREATE TABLE (e.g. PostgreSQL).
