C++ (Cpp) GetDatabaseWithName Beispiele

Beispiel #1

Datei: stats_aggregator.cpp Projekt: ranxian/peloton

storage::DataTable *StatsAggregator::GetMetricTable(std::string table_name) {
  auto catalog = catalog::Catalog::GetInstance();
  PL_ASSERT(catalog->GetDatabaseCount() > 0);
  storage::Database *catalog_database =
      catalog->GetDatabaseWithName(CATALOG_DATABASE_NAME);
  PL_ASSERT(catalog_database != nullptr);
  auto metrics_table = catalog_database->GetTableWithName(table_name);
  PL_ASSERT(metrics_table != nullptr);
  return metrics_table;
}

Beispiel #2

Datei: catalog_test.cpp Projekt: eric-haibin-lin/peloton-1

TEST_F(CatalogTests, BootstrappingCatalog) {
  auto catalog = catalog::Catalog::GetInstance();
  EXPECT_EQ(catalog->GetDatabaseCount(), 1);
  storage::Database *database =
      catalog->GetDatabaseWithName(CATALOG_DATABASE_NAME);
  EXPECT_NE(database, nullptr);

  // Check metric tables
  auto db_metric_table = database->GetTableWithName(DATABASE_METRIC_NAME);
  EXPECT_NE(db_metric_table, nullptr);
}

Beispiel #3

Datei: catalog_test.cpp Projekt: foche/peloton

TEST_F(CatalogTests, BootstrappingCatalog) {
  auto catalog = catalog::Catalog::GetInstance();
  catalog->Bootstrap();
  EXPECT_EQ(1, storage::StorageManager::GetInstance()->GetDatabaseCount());
  auto &txn_manager = concurrency::TransactionManagerFactory::GetInstance();
  auto txn = txn_manager.BeginTransaction();
  storage::Database *database =
      catalog->GetDatabaseWithName(CATALOG_DATABASE_NAME, txn);
  txn_manager.CommitTransaction(txn);
  EXPECT_NE(nullptr, database);
  // Check database metric table
  auto db_metric_table =
      database->GetTableWithName(DATABASE_METRICS_CATALOG_NAME);
  EXPECT_NE(nullptr, db_metric_table);
