Renato Haeberli commented on SOLR-17635:
----------------------------------------
Ah right, my mind was still with the other ticket, where we want to move from
NamedList.asShallowMap to a SimpleOrderedMap.
But the questions remain, should the deserialization into a SimpleOrderedMap
be the new default behavior, or should the default behavior be as it is
currently with LinkedHashMap?
> javabin should deserialize maps as SimpleOrderedMap

> Key: SOLR-17635
> URL: https://issues.apache.org/jira/browse/SOLR-17635
> Project: Solr
> Issue Type: Improvement
> Reporter: David Smiley
> Priority: Major
>
> Once SimpleOrderedMap actually implements Map (SOLR-17623), Solr's "javabin"
> format should deserialize all maps as a SimpleOrderedMap. This will make it
> easier to transition away from NamedList/SimpleOrderedMap in responses (such
> as to a Map or MapWriter) without worry of impacting javabin clients that
> still expect a NamedList.
> It may also increase deserialization performance & lower memory at the
> expense of any former Maps (thus were deserialized as LinkedHashMap, O(1)
> lookup) becoming O(N) lookup.
