Detailed Description

class for a per-database catalog. also includes metadata for the current database and the current user.

Catalog

Definition at line 143 of file Catalog.h.

Member Typedef Documentation

using Catalog_Namespace::Catalog::ColumnDescriptorsForRoll = std::vector<std::pair<ColumnDescriptor*, ColumnDescriptor*>>

protected

Definition at line 738 of file Catalog.h.

Constructor & Destructor Documentation

Catalog_Namespace::Catalog::Catalog	(	const std::string &	basePath,
		const DBMetadata &	curDB,
		std::shared_ptr< Data_Namespace::DataMgr >	dataMgr,
		const std::vector< LeafHostInfo > &	string_dict_hosts,
		std::shared_ptr< Calcite >	calcite,
		bool	is_new_db
	)

Constructor - takes basePath to already extant data directory for writing.

Parameters

basePath	directory path for writing catalog
dbName	name of the database
fragmenter	Fragmenter object metadata - expects for this directory to already exist

Catalog_Namespace::Catalog::Catalog ( )

Constructor builds a hollow catalog used during constructor of other catalogs.

Definition at line 174 of file Catalog.cpp.

174 {}

Catalog_Namespace::Catalog::~Catalog ( )

Destructor - deletes all ColumnDescriptor and TableDescriptor structures which were allocated on the heap and writes Catalog to Sqlite.

Definition at line 234 of file Catalog.cpp.

References basePath_, columnDescriptorMap_, currentDB_, Catalog_Namespace::DBMetadata::dbName, g_serialize_temp_tables, Catalog_Namespace::anonymous_namespace{Catalog.cpp}::table_json_filepath(), and tableDescriptorMap_.

                   {
