Lightweight::SqlMigration::MigrationRelease Struct Reference

#include <SqlMigration.hpp>

Public Attributes
std::string	version
	Human-readable version string, e.g. "6.7.0".
MigrationTimestamp	highestTimestamp
	Highest migration timestamp contained in this release (inclusive).

Detailed Description

Associates a software release with the highest migration timestamp present at release time.

Releases are declared in source (typically a migration plugin) via LIGHTWEIGHT_SQL_RELEASE(version, highestTimestamp). They let tools answer questions like "which migrations belong to release 6.7.0?" or "roll back everything applied after 6.7.0".

The highestTimestamp is an inclusive upper bound: a migration M belongs to the release iff prev_release_ts < M.timestamp <= highestTimestamp, where prev_release_ts is the previous release's timestamp (or 0 if there is none).
