Capabilities for BigQuery

This section lists the Capabilities of Data Source Solutions DSS when using 'BigQuery'. For more information about the pre-requisites, access privileges, and other configuration requirements, see BigQuery Requirements.

Capture

DSS does not support Capture changes from location on BigQuery.

Repository Database

DSS does not support Repository database on BigQuery.

Integrate

DSS supports the following capabilities on BigQuery:

• Integrate changes into location (BigQuery version 2).
• Burst integration (Integrate with parameter Method=BURST) (BigQuery version 2).
• Append integration into TimeKey (Integrate with parameter Method=APPEND) (BigQuery version 2).
• Integrate with parameter BurstCommitFrequency (BigQuery version 2).
• Continuous integration (Integrate with parameter Method=CONTINUOUS) (BigQuery version 2).
• ColumnProperties with parameter SoftDelete (BigQuery version 2).
• Bulk load requires a staging area (location property Staging_Directory) (BigQuery version 2).
• Creation and update of DSS state tables (BigQuery version 2).

DSS does not support the following capabilities on BigQuery:

• Tables without a key and without TableProperties with NoDuplicateRows for continuous integration.
• Continuous integrate with parameter OnErrorSaveFailed.
• Disable/enable database triggers during integrate (with parameter NoTriggerFiring).
• Integrate with parameter DbProc.

Bi-directional Replication

DSS does not support Bi-directional Replication on BigQuery.

Refresh and Compare

DSS supports the following capabilities on BigQuery:

• dssrefresh or dsscompare from source location (BigQuery version 2).
• dssrefresh into target location (BigQuery version 2).
• Isolated table dssrefresh (option -i) into target location (BigQuery version 2).

Other Capabilities

DSS supports the following capabilities on BigQuery:

• International table and column names where DBMS is not configured with UTF-8 encoding (BigQuery version 2).
• Always treat DBMS table names and column names as case sensitive, even if not configured (equivalent to location property Case_Sensitive_Names always set to TRUE) (BigQuery version 2).
• Always treat DBMS schema names case sensitive (BigQuery version 2).

DSS does not support the following capabilities on BigQuery:

• Use distribution key for parallelizing changes within a table (ColumnProperties with parameter DistributionKey).
• Lossless binary float datatypes. No data loss when transporting float values (because base 2 fractions are never converted to base 10). The values for these datatypes, when selected back from the database, might be slightly different from the ones that were inserted. This leads to Compare differences..
