Method Detail
-
fieldName
public final 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.
- Returns:
- 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.

-
functionSpec
public final String functionSpec()
Specifies the function used to partition data on the target. The accepted values for this parameter are:
-
identity- Uses source values directly without transformation -
year- Extracts the year from timestamp values (e.g., 2023) -
month- Extracts the month from timestamp values (e.g., 2023-01) -
day- Extracts the day from timestamp values (e.g., 2023-01-15) -
hour- Extracts the hour from timestamp values (e.g., 2023-01-15-14)
- Returns:

are:
-
identity- Uses source values directly without transformation -
year- Extracts the year from timestamp values (e.g., 2023) -
month- Extracts the month from timestamp values (e.g., 2023-01) -
day- Extracts the day from timestamp values (e.g., 2023-01-15) -
hour- Extracts the hour from timestamp values (e.g., 2023-01-15-14)

conversionSpec
public final 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
ConversionSpecwhen 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
identitypartition 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.
