Description
|
Client Id
|
Specifies the client ID obtained from the Google Developers Console.
|
Client Secret
|
Specifies the client secret obtained from the Google Developers Console.
|
Connection Lifetime
|
Specifies the maximum lifetime (in seconds) of a connection. When a connection is returned to the pool, its creation time is compared with the current time, and the connection is destroyed if that time span exceeds the value specified by Connection Lifetime. The default value is 0 (connection always returns to pool).
|
Connection Timeout
|
Specifies the length of time (in seconds) to wait for a connection to the server before terminating the attempt and generating an error. The default value is 60.
|
Data Set Id
|
Specifies the unique Id of a Dataset you want to connect to.
|
Default Cloud Storage Bucket
|
Specifies a bucket to use for temporary CSV files when loading data to Google BigQuery. The files are automatically deleted after loading is finished.
|
Default Command Timeout
|
Specifies the time in seconds to wait while trying to execute a command before terminating the attempt and generating an error. 0 indicates no limit.
|
Failover Retries
|
Specifies the number of retries to perform a command if it fails because of an exception. The default value is 7.
|
Initialization Command
|
Specifies a data source-specific command to execute immediately after the connection is established.
|
Local SQL Engine
|
Determines whether to enable local SQL processing (enabled by default). Local SQL processing allows performing complex SELECT statements that cannot be directly compiled to Google BigQuery API calls. In this case, the data from the mentioned cloud objects is queried to the local cache, and then the query is performed against the cache.
If local SQL processing is disabled, only simple SELECT statements that can be directly translated into Google BigQuery API calls can be used. More complex SELECT statements will fail.
|
Max Pool Size
|
Specifies the maximum number of connections allowed in the pool. Setting the Max Pool Size value in the connection string can affect performance. The default value is 100.
|
Min Pool Size
|
Specifies the minimum number of connections allowed in the pool. The default value is 0.
|
NormalizeDbNames
|
Determines whether database object names are normalized when retrieved from the database.
|
Persist Security Info
|
Indicates if security-sensitive information, such as the password, is not returned as part of the connection if the connection is open or has ever been in an open state.
|
Pooling
|
Specifies whether, by default, the connection is drawn from the appropriate pool or is created and added to the appropriate pool.
|
Primary Key Column
|
Specifies the name of a column that is considered as a primary column of a table.
Google BigQuery does have primary keys. You should specify the name of a column that Devart SSIS Data Flow Components will consider a primary key. Note that it is the same for all the tables accessed via this connection, and thus, all the BigQuery tables you are going to access via this connection must have a column with the same name, for example, ID, that is considered a primary key.
|
Project ID
|
Specifies the unique ID of a Google Cloud Platform Project associated with the connection.
|
Proxy Host
|
Specifies the host name or IP address of the proxy server.
|
Proxy Password
|
Specifies the password for the proxy server account.
|
Proxy Port
|
Specifies the port number of the proxy server. The default value is 3128.
|
Proxy User
|
Specifies the proxy server account name.
|
Readonly
|
Indicates whether the connection is read-only (allows only SELECT statements).
|
Refresh Token
|
Stores the refresh token returned from the authorization code exchange.
|
Run Once Command
|
Specifies a command to execute immediately after establishing the connection. Unlike Initialization Command, it is not executed for connections obtained from the connection pool.
|
Token Server
|
Is not used for Google BigQuery.
|
Use Legacy SQL
|
Determines whether to use BigQuery's legacy SQL dialect. The default value is false.
|
UTC Dates
|
Determines whether to treat date values as UTC dates. The default value is false.
