If a table with the same ID but a different type exists, it is still an error. Supported values: TRUE FALSE The default value is FALSE. See Also: Constant Field Values TRUE public static final String TRUE See Also: Constant Field Values FALSE public static final String FALSE See Also: Constant Field Values CREATE_TEMP_TABLE public static final String CREATE_TEMP_TABLE If TRUE, a unique temporary table name will be generated in the sys_temp schema and used in place of tableName. If IS_RESULT_TABLE is TRUE, then this is always allowed even if the caller does not have permission to create tables. The generated name is returned in QUALIFIED_TABLE_NAME. Supported values: TRUE FALSE The default value is FALSE. See Also: Constant Field Values COLLECTION_NAME public static final String COLLECTION_NAME [DEPRECATED--please specify the containing schema as part of tableName and use GPUdb.createSchema to create the schema if non-existent] Name of a schema which is to contain the newly created table. If the schema is non-existent, it will be automatically created. See Also: Constant Field Values IS_COLLECTION public static final String IS_COLLECTION [DEPRECATED--please use GPUdb.createSchema to create a schema instead] Indicates whether to create a schema instead of a table. Supported values: TRUE FALSE The default value is FALSE. See Also: Constant Field Values DISALLOW_HOMOGENEOUS_TABLES public static final String DISALLOW_HOMOGENEOUS_TABLES No longer supported; value will be ignored. Supported values: TRUE FALSE The default value is FALSE. See Also: Constant Field Values IS_REPLICATED public static final String IS_REPLICATED Affects the distribution scheme for the table's data. If TRUE and the given type has no explicit shard key defined, the table will be replicated. If FALSE, the table will be sharded according to the shard key specified in the given typeId, or randomly sharded, if no shard key is specified. Note that a type containing a shard key cannot be used to create a replicated table. Supported values: TRUE FALSE The default value is FALSE. See Also: Constant Field Values FOREIGN_KEYS public static final String FOREIGN_KEYS Semicolon-separated list of foreign keys, of the format '(source_column_name [, ...]) references target_table_name(primary_key_column_name [, ...]) [as foreign_key_name]'. See Also: Constant Field Values FOREIGN_SHARD_KEY public static final String FOREIGN_SHARD_KEY Foreign shard key of the format 'source_column references shard_by_column from target_table(primary_key_column)'. See Also: Constant Field Values PARTITION_TYPE public static final String PARTITION_TYPE Partitioning scheme to use. Supported values: RANGE: Use range partitioning. INTERVAL: Use interval partitioning. LIST: Use list partitioning. HASH: Use hash partitioning. SERIES: Use series partitioning. See Also: Constant Field Values RANGE public static final String RANGE Use range partitioning. See Also: Constant Field Values INTERVAL public static final String INTERVAL Use interval partitioning. See Also: Constant Field Values LIST public static final String LIST Use list partitioning. See Also: Constant Field Values HASH public static final String HASH Use hash partitioning. See Also: Constant Field Values SERIES public static final String SERIES Use series partitioning. See Also: Constant Field Values PARTITION_KEYS public static final String PARTITION_KEYS Comma-separated list of partition keys, which are the columns or column expressions by which records will be assigned to partitions defined by PARTITION_DEFINITIONS. See Also: Constant Field Values PARTITION_DEFINITIONS public static final String PARTITION_DEFINITIONS Comma-separated list of partition definitions, whose format depends on the choice of PARTITION_TYPE. See range partitioning, interval partitioning, list partitioning, hash partitioning, or series partitioning for example formats. See Also: Constant Field Values IS_AUTOMATIC_PARTITION public static final String IS_AUTOMATIC_PARTITION If TRUE, a new partition will be created for values which don't fall into an existing partition. Currently only supported for list partitions. Supported values: TRUE FALSE The default value is FALSE. See Also: Constant Field Values TTL public static final String TTL Sets the TTL of the table specified in tableName. See Also: Constant Field Values CHUNK_SIZE public static final String CHUNK_SIZE Indicates the number of records per chunk to be used for this table. See Also: Constant Field Values CHUNK_COLUMN_MAX_MEMORY public static final String CHUNK_COLUMN_MAX_MEMORY Indicates the target maximum data size for each column in a chunk to be used for this table. See Also: Constant Field Values CHUNK_MAX_MEMORY public static final String CHUNK_MAX_MEMORY Indicates the target maximum data size for all columns in a chunk to be used for this table. See Also: Constant Field Values IS_RESULT_TABLE public static final String IS_RESULT_TABLE Indicates whether the table is a memory-only table. A result table cannot contain columns with store_only or text_search data-handling or that are non-charN strings, and it will not be retained if the server is restarted. Supported values: TRUE FALSE The default value is FALSE. See Also: Constant Field Values STRATEGY_DEFINITION public static final String STRATEGY_DEFINITION The tier strategy for the table and its columns. See Also: Constant Field Values LOAD_VECTORS_POLICY public static final String LOAD_VECTORS_POLICY Set startup data loading scheme for the table. Supported values: ALWAYS: Load as much vector data as possible into memory before accepting requests. LAZY: Load the necessary vector data at start, and load the remainder lazily. ON_DEMAND: Load vector data as requests use it. SYSTEM: Load vector data using the system-configured default. The default value is SYSTEM. See Also: Constant Field Values ALWAYS public static final String ALWAYS Generate as much primary key index data as possible before accepting requests. See Also: Constant Field Values LAZY public static final String LAZY Generate the necessary primary key index data at start, and load the remainder lazily. See Also: Constant Field Values ON_DEMAND public static final String ON_DEMAND Generate primary key index data as requests use it. See Also: Constant Field Values SYSTEM public static final String SYSTEM Generate primary key index data using the system-configured default. See Also: Constant Field Values BUILD_PK_INDEX_POLICY public static final String BUILD_PK_INDEX_POLICY Set startup primary-key index generation scheme for the table. Supported values: ALWAYS: Generate as much primary key index data as possible before accepting requests. LAZY: Generate the necessary primary key index data at start, and load the remainder lazily. ON_DEMAND: Generate primary key index data as requests use it. SYSTEM: Generate primary key index data using the system-configured default. The default value is SYSTEM.
