Subject [jira] [Updated] (HUDI-617) Add support for data types convertible to String in TimestampBasedKeyGenerator
Date Tue, 18 Feb 2020 08:06:00 GMT

     [ 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.
