{
_connectionInfo = connectionInfo;
_connectionFactory = connectionFactory;
_provider = provider;
_providerMetadata = providerMetadata;
_versioningTableName = versioningTableName;
_sqlDispatcher = sqlDispatcher;
_versioningTableExists = new Lazy<bool>(() =>
{
int exists;
using (IDbConnection connection = connectionFactory.OpenConnection(connectionInfo))
{
IDbCommand command = connection.CreateCommand();
command.CommandTimeout = 0; // do not timeout; the client is responsible for not causing lock-outs
command.CommandText = provider.ExistsTable(connection.Database, _versioningTableName);
Log.Verbose(LogCategory.Sql, command.CommandText);
exists = Convert.ToInt32(command.ExecuteScalar(), CultureInfo.InvariantCulture);
