But there are other concerns to be raised on using a denormalized schema.

KiokuDB doesn't so much use a denormalized schema as it uses no schema at all. Using the DBI backend for Kioku your schema basically looks like this:

sqlite> .tables entries gin_index sqlite> .schema entries CREATE TABLE entries ( id varchar NOT NULL, data blob NOT NULL, class varchar, root boolean NOT NULL, tied char(1), PRIMARY KEY (id) ); sqlite> .schema gin_index CREATE TABLE gin_index ( id varchar NOT NULL, value varchar NOT NULL ); CREATE INDEX gin_index_ids_gin_index ON gin_index (id); CREATE INDEX gin_index_values_gin_index ON gin_index (value);
I suspect (but I don't know for sure) that with this we can still take advantage of the concurrency inherent in the RDBMS we use.
