Ryan Blue commented on AVRO-1497:
---------------------------------
bq. Did you average the times over a few runs?
No, I haven't but I'll run a few more tests. It looks like most of the ones
that have changed more than 5% are either not going through the data model
(like {{ValidatingRecordRead}} and {{GenericNestedFake_Write}}) or are for
other reasons likely due to variance ({{IntRead}} is small,
{{GenericStringsWrite}} is faster). The ones I'm still not sure about are the
reflect double and long array tests I noted above, but those are reading
approximately the same amount of data and going through the same methods, other
than the underlying decoder. I'll run some more tests, but I don't see a reason
for either performance gain or loss. Overall I think that these runs don't flag
any concerns with the addition, which makes sense because it is essentially a
hash table lookup and a couple additional null tests.
> Add LogicalType support to Java

> Key: AVRO-1497
> URL: https://issues.apache.org/jira/browse/AVRO-1497
> Project: Avro
> Issue Type: New Feature
> Components: java
> Reporter: Ryan Blue
> Assignee: Zoltan Farkas
> Fix For: 1.7.8
>
> Attachments: Logical Types Performance Comparison - Sheet1.csv
>
>
> AVRO-1402 updates the Avro spec to include logical types, which are stored as
> existing types but interpreted as others. The next step is to implement
> LogicalType (in Java) that provides tools to attach a logical type to a
> schema, read a logical type, and validate logical types.
