Capabilities for Aurora PostgreSQL

This section lists the Capabilities of Fivetran HVR when using 'Aurora PostgreSQL'. For more information about the pre-requisites, access privileges, and other configuration requirements, see Aurora PostgreSQL Requirements.

Capture

HVR supports the following capabilities on Aurora PostgreSQL:

• Capture changes from location (Aurora PostgreSQL from version 10 to version 16).
• Log-based capture (capture from DBMS logging system) (Aurora PostgreSQL from version 10 to version 16).
• Log-based capture of tables without a primary key (Aurora PostgreSQL from version 10 to version 16).
• Access to logs using SQL interface (Aurora PostgreSQL from version 10 to version 16).
• Log-based capture of tables with LOB column (Aurora PostgreSQL from version 10 to version 16).
• Multiple log-based capture jobs can capture from same database (Aurora PostgreSQL from version 10 to version 16).
• Log-based capture checkpointing using location property Capture_Checkpoint_Frequency (Aurora PostgreSQL from version 10 to version 16).

HVR does not support the following capabilities on Aurora PostgreSQL:

• Capture from Archive log files only.
• Log-based capture of DDL statements using action AdaptDDL.
• Direct access to logs on a file system.
• Log-based capture from hidden rowid/RRN column (ColumnProperties with parameter CaptureFromRowId).
• Rewind log-based capture to specific time (hvractivate option -i).
• Online refresh using accurate LSN/SCN.
• Populates column hvr_cap_user for use in ColumnProperties {hvr_cap_user} substitutions.
• Log-based capture of truncate table statements.
• Capture from tables with basic compression.
• Read archives from an alternative directory (location property Archive_Log_Path on the capture location).
• Trigger-based capture (location property Capture_Method=DB_TRIGGER on the capture location).

Repository Database

HVR supports Repository database on Aurora PostgreSQL.

Integrate

HVR supports the following capabilities on Aurora PostgreSQL:

• Integrate changes into location (Aurora PostgreSQL from version 10 to version 16).
• Burst integration (Integrate with parameter Method=BURST) (Aurora PostgreSQL from version 10 to version 16).
• Integrate with parameter BurstCommitFrequency (Aurora PostgreSQL from version 10 to version 16).
• Continuous integration (Integrate with parameter Method=CONTINUOUS) (Aurora PostgreSQL from version 10 to version 16).
• Tables without a key and without TableProperties with NoDuplicateRows for continuous integration (Aurora PostgreSQL from version 10 to version 16).
• Continuous integrate with parameter OnErrorSaveFailed (Aurora PostgreSQL from version 10 to version 16).
• ColumnProperties with parameter SoftDelete (Aurora PostgreSQL from version 10 to version 16).
• Creation and update of HVR state tables (Aurora PostgreSQL from version 10 to version 16).

HVR does not support the following capabilities on Aurora PostgreSQL:

• Disable/enable database triggers during integrate (with parameter NoTriggerFiring).
• Integrate with parameter DbProc.

Bi-directional Replication

HVR supports the following capabilities on Aurora PostgreSQL:

• Detection of changes made by HVR in a bidirectional channel to prevent loop-back (Aurora PostgreSQL from version 10 to version 16, state table needs to be created before replication starts).
• CollisionDetect with parameter TimestampColumn (Aurora PostgreSQL from version 10 to version 16).

HVR does not support the following capabilities on Aurora PostgreSQL:

• CollisionDetect with Log-based Capture (without parameter TimestampColumn).

Refresh and Compare

HVR supports the following capabilities on Aurora PostgreSQL:

• hvrrefresh or hvrcompare from source location (Aurora PostgreSQL from version 10 to version 16).
• hvrrefresh into target location (Aurora PostgreSQL from version 10 to version 16).
• Row-wise hvrrefresh into target location (option -g) (Aurora PostgreSQL from version 10 to version 16).

Other Capabilities

HVR supports the following capabilities on Aurora PostgreSQL:

• Call database procedure dbproc during replication jobs (AgentPlugin with parameter DbProc) (Aurora PostgreSQL from version 10 to version 16).
• International table and column names where DBMS is not configured with UTF-8 encoding (Aurora PostgreSQL from version 10 to version 16).
• 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) (Aurora PostgreSQL from version 10 to version 16).
• Always treat DBMS schema names case sensitive (Aurora PostgreSQL from version 10 to version 16).

HVR does not support the following capabilities on Aurora PostgreSQL:

• Use distribution key for parallelizing changes within a table (ColumnProperties with parameter DistributionKey).
• Distinguish and support capture from 'materialized views'.
