-------------------------------
Summary: Add support for data types convertible to String in
TimestampBasedKeyGenerator
Key: HUDI-617
URL: https://issues.apache.org/jira/browse/HUDI-617
Project: Apache Hudi (incubating)
Issue Type: Improvement
Components: Utilities
Reporter: Amit Singh
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
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.
