> Optimize JavabinCodec to use byte[] backed CharSequence instead of String

> Key: SOLR-12924
> URL: https://issues.apache.org/jira/browse/SOLR-12924

> Issue Type: Improvement
> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: Noble Paul

>
> 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[]
