Functions

func AdminBoundaryDefinition added in v0.9.0 

func AdminBoundaryDefinition(adminConfig config.AdminConfig) boundarymodel.Definition

Types

type BoundaryPools 

type BoundaryPools struct {
	Boundary string
	Write    *sqlitex.Pool
	Read     *sqlitex.Pool
}

BoundaryPools owns the connections backing one boundary database.

Write pool is sized to 1: SQLite serializes writers anyway via its file lock, so a single in-flight writer queues callers in Go and avoids SQLITE_BUSY churn. Read pool is sized to runtime.NumCPU() — under WAL, readers run concurrently with the single writer. In memory mode, Read and Write share one single-connection pool: the connection owns the private database and serializes transactions without shared-cache locks.

func OpenBoundaryPools 

func OpenBoundaryPools(ctx context.Context, dir, boundary string) (*BoundaryPools, error)

OpenBoundaryPools opens write+read pools for one boundary at {dir}/{boundary}.db. Migrations are applied on the first connection drawn from the write pool.

func OpenBoundaryPoolsWithConfig 

func OpenBoundaryPoolsWithConfig(ctx context.Context, sqliteCfg config.SqliteConfig, boundary string) (*BoundaryPools, error)

func OpenMetadataPoolsWithConfig 

func OpenMetadataPoolsWithConfig(ctx context.Context, sqliteCfg config.SqliteConfig, boundary string) (*BoundaryPools, error)

func (*BoundaryPools) Close 

func (b *BoundaryPools) Close() error

type BoundaryRegistry added in v0.8.0 

type BoundaryRegistry struct {
	// contains filtered or unexported fields
}

BoundaryRegistry is the shared, concurrency-safe source of SQLite event and metadata pools. Every boundary-aware adapter in one runtime uses the same registry so provisioning becomes visible atomically.

func NewBoundaryRegistry added in v0.8.0 

func NewBoundaryRegistry(pools, metadataPools map[string]*BoundaryPools) *BoundaryRegistry

type DatabaseRuntime added in v0.8.0 

type DatabaseRuntime struct {
	SaveEvents        eventstore.EventsSaver
	GetEvents         eventstore.EventsRetriever
	LockProvider      eventstore.LockProvider
	AdminDB           common.DB
	SignalProvider    func(string) eventstore.EventSignal
	ProvisionBoundary func(context.Context, boundarymodel.Definition) error
	InstallBoundary   func(context.Context, boundarymodel.Definition) error
}

func InitializeSqliteDatabaseRuntime added in v0.8.0 

func InitializeSqliteDatabaseRuntime(
	ctx context.Context,
	sqliteCfg config.SqliteConfig,
	adminCfg config.AdminConfig,
	js jetstream.JetStream,
	logger logging.Logger,
) (*DatabaseRuntime, error)

func InitializeSqliteDatabaseRuntimeWithLockProvider added in v0.8.0 

func InitializeSqliteDatabaseRuntimeWithLockProvider(
	ctx context.Context,
	sqliteCfg config.SqliteConfig,
	adminCfg config.AdminConfig,
	lockProvider eventstore.LockProvider,
	logger logging.Logger,
) (*DatabaseRuntime, error)

type SqliteAdminDB 

type SqliteAdminDB struct {
	// contains filtered or unexported fields
}

func NewSqliteAdminDB 

func NewSqliteAdminDB(pools map[string]*BoundaryPools, adminBoundary string, logger logging.Logger) *SqliteAdminDB

func (a *SqliteAdminDB) CreateBoundaryIndex(
	ctx context.Context,
	boundary, name string,
	fields []eventstore.BoundaryIndexField,
	conditions []eventstore.BoundaryIndexCondition,
	combinator string,
) (err error)

CreateBoundaryIndex builds a partial expression index over orisun_es_event.data JSON keys. Index name = "{name}_idx" inside the boundary's database.

func (*SqliteAdminDB) DeleteUser 

func (a *SqliteAdminDB) DeleteUser(ctx context.Context, id string) error

func (*SqliteAdminDB) DropBoundaryIndex 

func (a *SqliteAdminDB) DropBoundaryIndex(ctx context.Context, boundary, name string) (err error)

func (*SqliteAdminDB) GetEventsCount 

func (a *SqliteAdminDB) GetEventsCount(ctx context.Context, boundary string) (int, error)

func (*SqliteAdminDB) GetProjectorLastPosition 

func (a *SqliteAdminDB) GetProjectorLastPosition(ctx context.Context, projectorName string) (*eventstore.Position, error)

func (*SqliteAdminDB) GetUserById 

func (a *SqliteAdminDB) GetUserById(ctx context.Context, id string) (eventstore.User, error)

func (*SqliteAdminDB) GetUserByUsername 

func (a *SqliteAdminDB) GetUserByUsername(ctx context.Context, username string) (eventstore.User, error)

func (*SqliteAdminDB) GetUsersCount 

func (a *SqliteAdminDB) GetUsersCount(ctx context.Context) (uint32, error)

func (*SqliteAdminDB) ListAdminUsers 

func (a *SqliteAdminDB) ListAdminUsers(ctx context.Context) ([]*eventstore.User, error)

func (*SqliteAdminDB) ListBoundaryIndexes added in v0.9.3 

func (a *SqliteAdminDB) ListBoundaryIndexes(ctx context.Context, boundary string) ([]eventstore.BoundaryIndex, error)

func (*SqliteAdminDB) UpsertUser 

func (a *SqliteAdminDB) UpsertUser(ctx context.Context, user eventstore.User) error

type SqliteBoundaryProvisioner added in v0.8.0 

type SqliteBoundaryProvisioner struct {
	// contains filtered or unexported fields
}

SqliteBoundaryProvisioner is the SQLite adapter for the boundary provisioning slice. It opens and migrates both files, then publishes their pools to every adapter through one registry.

func NewSqliteBoundaryProvisioner added in v0.8.0 

func NewSqliteBoundaryProvisioner(
	sqliteCfg config.SqliteConfig,
	adminCfg config.AdminConfig,
	registry *BoundaryRegistry,
	saver *SqliteSaveEvents,
) *SqliteBoundaryProvisioner

type SqliteEventNotifier 

type SqliteEventNotifier struct {
	// contains filtered or unexported fields
}

func NewSqliteEventNotifier 

func NewSqliteEventNotifier() *SqliteEventNotifier

func NewSqliteEventNotifierWithWakeDelay 

func NewSqliteEventNotifierWithWakeDelay(wakeDelay time.Duration) *SqliteEventNotifier

func (*SqliteEventNotifier) Notify

func (*SqliteEventNotifier) Signal 

func (n *SqliteEventNotifier) Signal(boundary string) eventstore.EventSignal

type SqliteGetEvents 

type SqliteGetEvents struct {
	// contains filtered or unexported fields
}

func NewSqliteGetEvents

func (*SqliteGetEvents) GetBatch 

func (s *SqliteGetEvents) GetBatch(ctx context.Context, req *eventstore.GetEventsRequest) (eventstore.ReadEventBatch, error)

func (*SqliteGetEvents) GetLatestByCriteria 

func (s *SqliteGetEvents) GetLatestByCriteria(ctx context.Context, query eventstore.LatestByCriteriaQuery) (eventstore.LatestByCriteriaBatch, error)

GetLatestByCriteria returns the latest event per criterion plus the max observed position, all from ONE read snapshot: the per-criterion lookups run inside an explicit deferred read transaction, so under WAL every statement sees the same database state. Independent client reads cannot substitute — an event committing between them can hide below the observed max position.

func (*SqliteGetEvents) GetWriteContext added in v0.12.0 

func (s *SqliteGetEvents) GetWriteContext(ctx context.Context, req *orisun.GetWriteContextRequest) (*orisun.WriteContext, error)

type SqliteSaveEvents struct {
	// contains filtered or unexported fields
}

func NewSqliteSaveEvents 

func NewSqliteSaveEvents(pools map[string]*BoundaryPools, logger logging.Logger) *SqliteSaveEvents

NewSqliteSaveEvents constructs the saver with the package-default group-commit tuning. Use NewSqliteSaveEventsWithConfig to override.

func NewSqliteSaveEventsWithConfig 

func NewSqliteSaveEventsWithConfig(
	pools map[string]*BoundaryPools,
	logger logging.Logger,
	gcCfg config.SqliteGroupCommitConfig,
) (*SqliteSaveEvents, error)

func (*SqliteSaveEvents) SavePrepared 

func (s *SqliteSaveEvents) SavePrepared(
	ctx context.Context,
	events eventstore.PreparedEventBatch,
	boundary string,
	consistency []eventstore.ConsistencyCheck,
) (transactionID string, globalID int64, err error)
