----------------------------------
Summary: Parse timestamps in microsecond precision by
`to_timestamp`, `to_unix_timestamp`, `unix_timestamp`
Key: SPARK-29927
URL: https://issues.apache.org/jira/browse/SPARK-29927
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 2.4.4
Reporter: Maxim Gekk
Currently, the `to_timestamp`, `to_unix_timestamp`, `unix_timestamp` functions
uses SimpleDateFormat to parse strings to timestamps. SimpleDateFormat is able
to parse only in millisecond precision if an user specified `SSS` in a pattern.
The ticket aims to support parsing up to the microsecond precision.
