Interface Summary

Interface	Description
EventDdlTranslator	The dialect-specific fragments needed by the fixed event schema.
EventSchemaCreator	Applies the configured event schema action, propagating hard failures to the coordinator.

Class Summary

Class	Description
DialectEventDdlTranslator	Resolves DDL fragments on Hibernate 3.3 through 5.6.
DialectEventSchemaCreator	Creates missing event tables without bootstrapping another SessionFactory.
EventPersistenceBootstrap	Bootstraps event persistence using the factory and dialect already resolved by the scanner.
EventPersistenceContext	The EventPersistenceContext wires together the collaborators of the event persistence feature (EventStore, RuntimeEventAggregator and PersistentEventHandler) and manages their lifecycle.
EventPersistenceSettings	The EventPersistenceSettings is an immutable holder for the resolved event persistence configuration, computed once when the feature is activated.
EventPersistenceSettings.Builder	The EventPersistenceSettings.Builder for EventPersistenceSettings.
EventSchemaManager	Coordinates the lightweight strategy and the optional metadata fallback.
EventSchemaModel	Immutable JDBC model, deliberately independent of JPA and Hibernate metadata.
EventSchemaModel.ColumnModel
EventSchemaModel.ForeignKeyModel
EventSchemaModel.IndexModel
EventSchemaModel.TableModel
EventSignature	The EventSignature computes a stable key used to group runtime events for aggregation.
EventStore	The EventStore persists events into the database using plain JDBC and batched INSERT statements.
HostConnectionProvider	The HostConnectionProvider delegates all JDBC connection handling to the host application's ConnectionProvider, so that the short-lived SessionFactory used to generate the event tables borrows connections from the very same pool as the application.
HostWebAppConnectionProvider	A WebAppConnectionProvider that borrows and releases its JDBC connections through the host application's Hibernate connection provider.
HypersistenceOptimizerBootstrapEvent	The HypersistenceOptimizerBootstrapEvent is the canonical entity model for the ho_bootstrap_events table, which holds the configuration and mapping events detected during a single optimizer bootstrap.
HypersistenceOptimizerBootstrapRun	The HypersistenceOptimizerBootstrapRun is the canonical entity model for the ho_bootstrap_run table, which holds one row per optimizer bootstrap (a snapshot of the application at startup).
HypersistenceOptimizerRuntimeEvent	The HypersistenceOptimizerRuntimeEvent is the canonical entity model for the ho_runtime_events table, which holds the aggregated runtime events (one row per run, event signature and time window, carrying an occurrence count and, where available, the total and maximum durations).
MetadataEventSchemaCreator	The MetadataEventSchemaCreator creates, on demand, the database tables used by the event persistence feature.
MissingTableSchemaFilterProvider	The MissingTableSchemaFilterProvider limits the hbm2ddl schema management of the metadata fallback to the event tables that are missing.
PersistentEventHandler	The PersistentEventHandler is the EventHandler registered on the Config when the event persistence feature is enabled.
RuntimeEventAggregator	The RuntimeEventAggregator rolls up runtime events into time windows so that a slow operation triggered many times is summarized as a handful of rows (one per window) carrying an occurrence count and, when available, the total and maximum durations, rather than one row per occurrence.
RuntimeRollup	The RuntimeRollup is a mutable accumulator that aggregates all the runtime events sharing the same signature within the same time window.
SessionFactoryConnectionExecutor	The SessionFactoryConnectionExecutor runs the event persistence JDBC work against a Connection borrowed from the host application's Hibernate SessionFactory.
WebApp	The WebApp optionally starts the Hypersistence Optimizer WebApp inside the host application, so the events can be visualized without deploying a separate process.

Enum Summary

Enum	Description
EventCategory	The EventCategory classifies an Event based on the phase during which it is emitted, so that configuration and mapping events (detected once, at bootstrap) can be told apart from runtime events (emitted continuously while the application runs).
SchemaAction	The SchemaAction controls how the event persistence feature manages the database tables it uses.
