Types

type KeyValue

type KeyValue struct {
	DB *sql.DB

	// SetFunc is an optional func to use when REPLACE INTO does not exist
	SetFunc      func(*sql.DB, string, string) error
	BatchSetFunc func(*sql.Tx, string, string) error

	// PlaceHolderFunc optionally replaces ? placeholders
	// with the right ones for the rdbms in use.
	PlaceHolderFunc func(string) string

	// Serial determines whether a Go-level mutex protects DB from
	// concurrent access.  This isn't perfect and exists just for
	// SQLite, whose driver likes to return "the database is
	// locked" (camlistore.org/issue/114), so this keeps some
	// pressure off. But we still trust SQLite to deal with
	// concurrency in most cases.
	Serial bool

	// TablePrefix optionally provides a prefix for SQL table
	// names. This is typically "dbname.", ending in a period.
	TablePrefix string
	// contains filtered or unexported fields
}
