[jira] [Updated] (HUDI-617) Add support for data types convertible
to String in TimestampBasedKeyGenerator
[ https://issues.apache.org/jira/browse/HUDI-617?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Amit Singh updated HUDI-617:
----------------------------
Description:
Currently, TimestampBasedKeyGenerator only supports 4 data types for the partition key. They are Double, Long, Float and String. However, if the `avro.java.string` is not specified in the schema provided, Hudi throws the following error:
org.apache.hudi.exception.HoodieNotSupportedException: Unexpected type for partition field: org.apache.avro.util.Utf8
at org.apache.hudi.utilities.keygen.TimestampBasedKeyGenerator.getKey(TimestampBasedKeyGenerator.java:111)
at org.apache.hudi.utilities.deltastreamer.DeltaSync.lambda$readFromSource$f92c188c$1(DeltaSync.java:338)
....
It will be better if the support was more generalised to include the data types that provide method to convert them to String such as `Utf8` since all these methods implement the `CharSequence` interface.
