Csaba Ringhofer created IMPALA-7853: ---------------------------------------
Summary: Add support to read int64 NANO timestamps to the parquet scanner Key: IMPALA-7853 URL: https://issues.apache.org/jira/browse/IMPALA-7853 Project: IMPALA Issue Type: Improvement Components: Backend Reporter: Csaba Ringhofer Assignee: Csaba Ringhofer PARQUET-1387 added int64 timestamps with nanosecond precision. As 64 bits are not enough to represent the whole 1400..9999 range of Impala timestamps, so this new new type works with a limited range: 1677-09-21 00:12:43.145224192 .. 2262-04-11 23:47:16.854775807 UTC The benefit of the reduced range is that no validation is necessary during scanning, as every possible 64 bit value represents a valid timestamp in Impala. This may mean that this has the potential be the fastest way to store timestamps. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
