Detailed Description

A set of parameters for Kinetica.createTable.

Creates a new table. If a new table is being created, the type of the table is given by type_id, which must be the ID of a currently registered type (i.e. one created via Kinetica.createType).

A table may optionally be designated to use a replicated distribution scheme, or be assigned: foreign keys to other tables, a partitioning scheme, and/or a tier strategy.

Constructor & Destructor Documentation

CreateTableRequest() [1/2]

kinetica.CreateTableRequest.CreateTableRequest ( )

inline

Constructs a CreateTableRequest object with default parameters.

Definition at line 752 of file CreateTable.cs.

CreateTableRequest() [2/2]

kinetica.CreateTableRequest.CreateTableRequest ( string  table_name, string  type_id, IDictionary< string, string >  options = null  )

inline

Constructs a CreateTableRequest object with the specified parameters.

Parameters

table_name	Name of the table to be created, in [schema_name.]table_name format, using standard name resolution rules and meeting table naming criteria. Error for requests with existing table of the same name and type ID may be suppressed by using the NO_ERROR_IF_EXISTS option.
type_id	ID of a currently registered type. All objects added to the newly created table will be of this type.
options	Optional parameters. NO_ERROR_IF_EXISTS: If TRUE, prevents an error from occurring if the table already exists and is of the given type. 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. CREATE_TEMP_TABLE: If TRUE, a unique temporary table name will be generated in the sys_temp schema and used in place of table_name . 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. COLLECTION_NAME: [DEPRECATED–please specify the containing schema as part of table_name and use Kinetica.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. IS_COLLECTION: [DEPRECATED–please use Kinetica.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. DISALLOW_HOMOGENEOUS_TABLES: No longer supported; value will be ignored. Supported values: TRUE FALSE The default value is FALSE. 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 type_id , 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. 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]'. FOREIGN_SHARD_KEY: Foreign shard key of the format 'source_column references shard_by_column from target_table(primary_key_column)'. 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. 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. 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. 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. TTL: Sets the TTL of the table specified in table_name . CHUNK_SIZE: Indicates the number of records per chunk to be used for this table. CHUNK_COLUMN_MAX_MEMORY: Indicates the target maximum data size for each column in a chunk to be used for this table. CHUNK_MAX_MEMORY: Indicates the target maximum data size for all columns in a chunk to be used for this table. 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. STRATEGY_DEFINITION: The tier strategy for the table and its columns. 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. 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. The default value is an empty Dictionary.
