Google Cloud Bigtable sources in mappings

To read data from a Google Cloud Bigtable bucket, configure a Google Cloud Bigtable object as the Source transformation in a mapping.
Specify the name and description of the Google Cloud Bigtable source. Configure the source and advanced properties for the source object.
The following table describes the properties that you can configure for a Google Cloud Bigtable source:
Property
Description
Connection
Name of the Google Bigtable source connection.
Source Type
Type of the Google Cloud Bigtable source object available. You can read data to a single Google Cloud Bigtable source object.
Object
Name of the source object for the mapping.
You can set the tracing level in the advanced properties session to determine the amount of details that logs contain.
The following table describes the tracing levels that you can configure:
Tracing Level
Description
Terse
The Secure Agent logs initialization information, error messages, and notification of rejected data.
Normal
The Secure Agent logs initialization and status information, errors encountered, and skipped rows due to transformation row errors. Summarizes session results, but not at the level of individual rows.
Verbose Initialization
In addition to normal tracing, the Secure Agent logs additional initialization details, names of index and data files used, and detailed transformation statistics.
Verbose Data
In addition to verbose initialization tracing, the Secure Agent logs each row that passes into the mapping. Also notes where the Secure Agent truncates string data to fit the precision of a column and provides detailed transformation statistics.
When you configure the tracing level to verbose data, the Secure Agent writes row data for all rows in a block when it processes a transformation.
