Ability to store Reader / InputStream fields
--------------------------------------------
Key: LUCENE-1206
URL: https://issues.apache.org/jira/browse/LUCENE-1206
Project: Lucene - Java
Issue Type: New Feature
Components: Index
Reporter: Trejkaz
In some situations we would like to store the whole text, but the whole text
won't always fit in memory so we can't create a String. Likewise for storing
binary, it would sometimes be better if we didn't have to read into a byte[]
up-front (even when it doesn't use much memory, it increases the number of
copies made and adds burden to GC.)
FieldsWriter currently writes the length at the start of the chunks though, so
I don't know whether it would be possible to seek back and write the length
after writing the data.
It would also be useful to use this in conjunction with compression, both for
Reader and InputStream types. And when retrieving the field, it should be
possible to create a Reader without reading the entire String into memory
up-front.
