NAME

DBIO::ClickHouse::Test::Schema::Snapshot - Test result class -- a ReplacingMergeTree table for FINAL

VERSION

version 0.900004

DESCRIPTION

A ReplacingMergeTree(version) table, the engine that makes the final resultset attribute ("final" in DBIO::ClickHouse::SQLMaker) mean something: insert the same id twice and only FINAL collapses the two rows to the one with the higher version.

It is also the only source in DBIO::ClickHouse::Test::Schema whose engine_expression carries an argument, so the introspection of engine_full -- as opposed to system.tables.engine, which drops the argument -- is exercised by simply deploying this schema.
