Thomas Mueller commented on OAK-6911:
-------------------------------------
I think it's enough to change the place where binaries are written:
org.apache.jackrabbit.oak.segment.DefaultSegmentWriter:
{noformat}
private RecordId internalWriteStream(@NotNull InputStream stream) throws
IOException {
// Special case for short binaries (up to about 16kB):
// store them directly as small- or medium-sized value records
byte[] data = new byte[Segment.MEDIUM_LIMIT];
int n = read(stream, data, 0, data.length);
if (n < Segment.MEDIUM_LIMIT) { <<<<<==== this would need to be
changed
return writeValueRecord(n, data);
}
{noformat}
> Provide a way to tune inline size while storing binaries

> SegmentNodeStore currently inlines binaries of size less that 16KB
> (Segment.MEDIUM_LIMIT) even if external BlobStore is configured.
> Due to this behaviour quite a bit of segment tar storage consist of blob
> data. In one setup out of 370 GB segmentstore size 290GB is due to inlined
> binary. If most of this binary content is moved to BlobStore then it would
> allow same repository to work better in lesser RAM
> So it would be useful if some way is provided to disable this default
> behaviour and let BlobStore take control of inline size i.e. in presence of
> BlobStore no inlining is attempted by SegmentWriter.
