Jean Boussier 17acb771d8 Deduplicate various Active Record schema cache structures ... Real world database schemas contain a lot of duplicated data. Some column names like `id`, `created_at` etc can easily be repeated hundreds of times. Same for SqlTypeMetada, most database will contain only a limited number of possible combinations. This result in a lot of wasted memory. The idea here is to make these data sctructures immutable, use a registry to substitute similar instances with pre-existing ones.		2019-06-03 13:31:42 +02:00
