Rewrite Table

Write the input data flow out to a new table.

Runtime errors may occur, for example if a data value overflows the maximum allowed size of a field.

Note: The output table is overwritten each time the component is executed so do not use this component to output permanent data you do not want to overwrite.

Properties

Snowflake Properties
Property	Setting	Description
Name	String	A human-readable name for the component.
Warehouse	Select	Select the Snowflake Warehouse. The special value, [Environment Default], will use the warehouse defined in the Matillion ETL environment. For more information, read Virtual Warehouses.
Database	Select	Select the Snowflake database. The special value, [Environment Default], will use the database defined in the Matillion ETL environment. For more information, read Databases, Tables, & Views.
Schema	Select	Select the Snowflake schema. The special value, [Environment Default], will use the schema defined in the Matillion ETL environment. For more information, read Database, Schema, & Share DDL.
Target Table	String	Provide a new table name. Note: Previous versions of this component prepended t_ to the target table name to help avoid clashing with existing tables; however, this is no longer the case.
Order By	Column	Select the column(s) to sort by.
Order By	Sort Order	Set the corresponding column to be ordered ascending or descending. The default sort order is ascending.

Redshift Properties
Property	Setting	Description
Name	String	A human-readable name for the component.
Schema	Select	Select the table schema. The special value, [Environment Default] will use the schema defined in the environment. For more information on using multiple schemas, see this article.
Target Table	Select	Choose a target table name. Note: Older versions of this component prepended 't_' to the name to help avoid clashing with existing tables; however, this is no longer the case.
Table Sort Key	Select	This is optional, and specifies the columns from the input that should be set as the table's sort-key. Sort-keys are critical to good performance - see the Amazon Redshift documentation for more information.
Sort Key Options	Select	Choose the type of sort key to be used. Compound: A compound key is made up of all of the columns listed in the sort key definition, in the order they are listed. Most useful for tables that will be queried with filters using prefixes of the sort keys. Interleaved: An interleaved sort gives equal weight to each column, or subset of columns, in the sort key. Most useful for when multiple queries use different columns for filters.
Table Distribution Style	Select	Even: Distribute rows around the Redshift cluster evenly. All: Copy rows to all nodes in the Redshift cluster. Key: Distribute rows around the Redshift cluster according to the value of a key column. Table distribution is critical to good performance - see the Amazon Redshift documentation for more information.
Table Distribution Key	Select	This is only displayed if the Table Distribution Style is set to Key. It is the column used to determine which cluster node the row is stored on.

BigQuery Properties
Property	Setting	Description
Name	String	A human-readable name for the component.
Target Project	Text	Enter the name of the Google Cloud Platform Project that the table belongs to.
Dataset	Text	Enter the name of the Google Cloud Platform Dataset that the table belongs to.
Target Table	Select	Choose a target table name. Note: Older versions of this component prepended 't_' to the name to help avoid clashing with existing tables; however, this is no longer the case.

Synapse Properties
Property	Setting	Description
Name	String	A human-readable name for the component.
Schema	Select	Select the table schema. The special value, [Environment Default], will use the schema defined in the environment. For more information on schemas, please see the Azure Synapse documentation.
Table	String	Specify the name of the table to create. Note: This field is case-sensitive by default, since Matillion ETL uses quoted identifiers. For more information, please refer to the Azure Synapse documentation.
Distribution Style	Select	Select the distribution style Hash: This setting assigns each row to one distribution by hashing the value stored in the distribution_column_name. The algorithm is deterministic, meaning it always hashes the same value to the same distribution. The distribution column should be defined as NOT NULL, because all rows that have NULL are assigned to the same distribution. Replicate: This setting stores one copy of the table on each Compute node. For SQL Data Warehouse, the table is stored on a distribution database on each Compute node. For Parallel Data Warehouse, the table is stored in an SQL Server filegroup that spans the Compute node. This behavior is the default for Parallel Data Warehouse. Round Robin: Distributes the rows evenly in a round-robin fashion. This is the default behaviour. For more information, please read this article.
Distribution Column	Select	Select the column to act as the distribution column. This property is only available when the Distribution Style property is set to "Hash".
Partition Key	Select	Select the table's partition key. Table partitions determine how rows are grouped and stored within a distribution. For more information on table partitions, please refer to this article.
Index Type	Select	Select the table indexing type. Options include: Clustered: A clustered index may outperform a clustered columnstore table when a single row needs to be retrieved quickly. The disadvantage to using a clustered index is that only queries that benefit are the ones that use a highly selective filter on the clustered index column. Choosing this option prompts the Index Column Grid property. Clustered Column Store: This is the default setting. Clustered columnstore tables offer both the highest level of data compression and the best overall query performance, especially for large tables. Choosing this option prompts the Index Column Order property. Heap: Users may find that using a heap table is faster for temporarily landing data in Synapse SQL pool. This is because loads to heaps are faster than to index tables, and in some cases, the subsequent read can be done from cache. When a user is loading data only to stage it before running additional transformations, loading the table to a heap table is much faster than loading the data to a clustered columnstore table. For more information, please consult the Azure Synapse documentation.
Index Column Grid	Name	The name of each column.
Index Column Grid	Sort	Assign a sort orientation of either ascending (Asc) or descending (Desc).
Index Column Order	Multiple Select	Select the columns in the order to be indexed.

Delta Lake Properties
Property	Setting	Description
Name	String	A human-readable name for the component.
Catalog	Select	Select a Databricks Unity Catalog. The special value, [Environment Default], will use the catalog specified in the Matillion ETL environment setup. Selecting a catalog will determine which databases are available in the next parameter.
Database	Select	Select the Delta Lake database. The special value, [Environment Default], will use the database specified in the Matillion ETL environment setup.
Table	Select	The name of the output table.
Partition Keys	Column Select	Select any input columns to be used as partition keys.
Table Properties	Key	A metadata property within the table. These are expressed as key=value pairs.
Table Properties	Value	The value of the corresponding row's key.
Comment	String	A descriptive comment of the view.
