Interface IntegrationPartition.Builder

    • Method Detail

      • fieldName

        IntegrationPartition.Builder fieldName​(String fieldName)

        The field name used to partition data on the target. Avoid using columns that have unique values for each row (for example, `LastModifiedTimestamp`, `SystemModTimeStamp`) as the partition column. These columns are not suitable for partitioning because they create a large number of small partitions, which can lead to performance issues.

        Parameters:
        fieldName - The field name used to partition data on the target. Avoid using columns that have unique values for each row (for example, `LastModifiedTimestamp`, `SystemModTimeStamp`) as the partition column. These columns are not suitable for partitioning because they create a large number of small partitions, which can lead to performance issues.
        Returns:
        Returns a reference to this object so that method calls can be chained together.

      • functionSpec

        IntegrationPartition.Builder functionSpec​(String functionSpec)

        Specifies the function used to partition data on the target. The only accepted value for this parameter is `'identity'` (string). The `'identity'` function ensures that the data partitioning on the target follows the same scheme as the source. In other words, the partitioning structure of the source data is preserved in the target destination.

        Parameters:
        functionSpec - Specifies the function used to partition data on the target. The only accepted value for this parameter is `'identity'` (string). The `'identity'` function ensures that the data partitioning on the target follows the same scheme as the source. In other words, the partitioning structure of the source data is preserved in the target destination.
        Returns:
        Returns a reference to this object so that method calls can be chained together.

      • conversionSpec

        IntegrationPartition.Builder conversionSpec​(String conversionSpec)

        Specifies the timestamp format of the source data. Valid values are:

        • epoch_sec - Unix epoch timestamp in seconds

        • epoch_milli - Unix epoch timestamp in milliseconds

        • iso - ISO 8601 formatted timestamp

        Only specify ConversionSpec when using timestamp-based partition functions (year, month, day, or hour). Glue Zero-ETL uses this parameter to correctly transform source data into timestamp format before partitioning.

        Do not use high-cardinality columns with the identity partition function. High-cardinality columns include:

        • Primary keys

        • Timestamp fields (such as LastModifiedTimestamp, CreatedDate)

        • System-generated timestamps

        Using high-cardinality columns with identity partitioning creates many small partitions, which can significantly degrade ingestion performance.

        Parameters:
        conversionSpec - Specifies the timestamp format of the source data. Valid values are:

        • epoch_sec - Unix epoch timestamp in seconds

        • epoch_milli - Unix epoch timestamp in milliseconds

        • iso - ISO 8601 formatted timestamp

        Only specify ConversionSpec when using timestamp-based partition functions (year, month, day, or hour). Glue Zero-ETL uses this parameter to correctly transform source data into timestamp format before partitioning.

        Do not use high-cardinality columns with the identity partition function. High-cardinality columns include:

        • Primary keys

        • Timestamp fields (such as LastModifiedTimestamp, CreatedDate)

        • System-generated timestamps

        Returns:
        Returns a reference to this object so that method calls can be chained together.
