Noble Paul updated SOLR-12924:
------------------------------
Description:
javabin format uses {{UTF8}} format for String serialization and java Strings
are {{UTF16}} and java String always days a buffer copy of those {{UTF16}}
input.
So, what I propose is
* we create a byte[] backed {{CharSequence}} implementation say
{{Utf8CharSequence}}.
* Optionally, javabinCodec can should be able to return this
{{Utf8CharSequence}} instead of all Strings
* If a {{charAt()}} or {{toString()}} call is made to {{Utf8CharSequence}} it
creates a {{String}} and cache it
* When this {{Utf8CharSequence}} needs to be serialized again in {{javabin}}
format it should copy the underlying utf8 byte[]
