Class InsertRecordsFromFilesRequest.CreateTableOptions
java.lang.Object
com.gpudb.protocol.InsertRecordsFromFilesRequest.CreateTableOptions
Enclosing class:
A set of string constants for the
InsertRecordsFromFilesRequest parameter createTableOptions.
Options from GPUdb.createTable, allowing the structure of the table to be defined independently of the data source, when creating the target table

Field Details
IS_REPLICATED
Affects the distribution scheme for the table’s data. IfTRUEand the given table has no explicit shard key defined, the table will be replicated. IfFALSE, the table will be sharded according to the shard key specified in the givenTYPE_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:The default value isFALSE.See Also: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: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:PARTITION_KEYS
Comma-separated list of partition keys, which are the columns or column expressions by which records will be assigned to partitions defined byPARTITION_DEFINITIONS.See Also:PARTITION_DEFINITIONS
Comma-separated list of partition definitions, whose format depends on the choice ofPARTITION_TYPE. See range partitioning, interval partitioning, list partitioning, hash partitioning, or series partitioning for example formats.See Also:IS_RESULT_TABLE
Indicates whether the table is a memory-only table. A result table cannot contain columns with text_search data-handling, and it will not be retained if the server is restarted. Supported values:The default value isFALSE.See Also:
