-----------------------------------
Summary: split direct packed ints from in-ram ones
Key: LUCENE-5731
URL: https://issues.apache.org/jira/browse/LUCENE-5731
Project: Lucene - Core
Issue Type: Bug
Reporter: Robert Muir
Assignee: Robert Muir
Currently there is an oversharing problem in packedints that imposes too many
requirements on improving it:
* every packed ints must be able to be loaded directly, or in ram, or iterated
with.
* things like filepointers are expected to be adjusted (this is especially
stupid) in all cases
* lots of unnecessary abstractions
* versioning etc is complex
None of this flexibility is needed or buys us anything, and it prevents
performance improvements (e.g. i just want to add 3 bytes at the end of on-disk
streams to reduce the number of bytebuffer calls and thats seriously impossible
with the current situation).
