Ryan Blue created AVRO-1683:
-------------------------------
Summary: Add microsecond-precision time and timestamp logical type
specs
Key: AVRO-1683
URL: https://issues.apache.org/jira/browse/AVRO-1683
Project: Avro
Issue Type: Improvement
Components: spec
Reporter: Ryan Blue
Assignee: Ryan Blue
SQL engines that store data in Avro need to be able to store times and
timestamps to meet the SQL spec. For portability, those values should be
labelled so other readers can work with the data. I propose adding two new
logical types:
* time-micros: annotates a long, represents the number of microseconds from
midnight.
* timestamp-micros: annotates a long, represents the number of microseconds
from the unix epoch.
Like the other time types, these representations match the ones that were just
added to Parquet (PARQUET-200) to make implementations easier.
