# [DRILL-8421](https://issues.apache.org/jira/browse/DRILL-8421): Truncate parquet microsecond columns ## Description The metadata min and max values of parquet microsecond columns are truncated to milliseconds, which is the time unit expected by the initial file pruning during filtering. Also, `TIME_MICROS` columns are read as 64-bit values before they are truncated to 32-bit milliseconds values. Previously they were read as 32-bit values, causing values > `Integer.MAX_VALUE` to be incorrect. The second fix also addresses [DRILL-8423](https://issues.apache.org/jira/browse/DRILL-8423). ## Documentation Bugfix only, no documentation changes ## Testing Unit tests added in new test class `org.apache.drill.exec.store.parquet.TestMicrosecondColumns`. -- This is an automated message from the Apache Git Service.
