---------------------------------
Summary: Hudi Timestamp Write Precision Incorrect
Key: HUDI-9359
URL: https://issues.apache.org/jira/browse/HUDI-9359
Project: Apache Hudi
Issue Type: Bug
Reporter: Sagar Sumit
Fix For: 1.1.0
When upgrading our stack from Hudi 0.14.0 to 0.15.0, writes on new tables with
columns defined as {{logicalType: timestamp-millis}} are written into Parquet
as {{{}timestamp{}}}, which in Spark defaults to {{{}micro{}}}. This means data
read as the Long 1720631224939 (meant to represent 2024-07-10) will instead
write back into the parquet as a date in January, 1970.
Reproducible script in https://github.com/apache/hudi/issues/13233
