------------------------------------
Summary: PackedInts: convenience classes to write blocks of packed
ints
Key: LUCENE-4643
URL: https://issues.apache.org/jira/browse/LUCENE-4643
Project: Lucene - Core
Issue Type: Bug
Reporter: Adrien Grand
Assignee: Adrien Grand
Priority: Minor
It is often useful to divide a packed stream into fixed blocks which are all
compressed independently:
* if your sequence of ints is very large, you won't have to buffer everything
into memory to compute the required number of bits per value,
* the compression ratio will be better in case of rare extreme values.
The only drawback compared to the original PackedInts API is that the stream
cannot be directly used to deserialize a random-access PackedInts.Reader (but
for sequential access, this is just fine).
