Summary: Optimize JavabinCodec to use byte[] backed CHarSequence
instead of String
Key: SOLR-12924
URL: https://issues.apache.org/jira/browse/SOLR-12924
Project: Solr
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.
* Optionally, javabinCodec can should be able to return this CharSequence
instead of all Strings
* If a {{charAt()}} or {{toString()}} call is made to this {{CharSequence}} we
create a String and cache it
* When this {{CharSequence needs to be serialized again in javabin format it
should copy the underlying utf8 byte[]
