Michael McCandless commented on LUCENE-8601: -------------------------------------------- Thanks [~muralikpbhat]; can we make the {{FieldType}} attributes be {{null}} to start, and lazily create the {{HashMap}} the first time someone calls {{setAttribute}}? This way people who never use attributes won't pay any added cost (except the {{null}} check). > Adding attributes to IndexFieldType > ----------------------------------- > > Key: LUCENE-8601 > URL: https://issues.apache.org/jira/browse/LUCENE-8601 > Project: Lucene - Core > Issue Type: Improvement > Components: core/index > Affects Versions: 7.5 > Reporter: Murali Krishna P > Priority: Major > Attachments: LUCENE-8601.01.patch, LUCENE-8601.02.patch, > LUCENE-8601.patch > > > Today, we can write a custom Field using custom IndexFieldType, but when the > DefaultIndexingChain converts [IndexFieldType to > FieldInfo|https://github.com/apache/lucene-solr/blob/master/lucene/core/src/java/org/apache/lucene/index/DefaultIndexingChain.java#L662], > only few key informations such as indexing options and doc value type are > retained.
