Hi all
We have a big index and a little space in disk.
When optimize and all space is consumed, our index is corrupted.
segments file point to nonexistent files.
Enviroment:
java 1.4.2_04
W2000 SP4
Tomat 5.5.4
Bye,
Ernesto.

Hello, Otis.
There is a big difference when you use compound index format or
multiple files. I have tested it on the big index (45 Gb). When I used
compound file then optimize takes 3 times more space, b/c *.cfs needs
to be unpacked.
Now I do use non compound file format. It needs like twice as much
disk space.

Yes the final three files are: the .cfs (46.8MB), deletable (4
bytes),
and segments (29 bytes).

Hello,
Yes, that is how optimize works - copies all existing index
segments into one unified index segment, thus optimizing it.
see hit #1:

However, three times the space sounds a bit too much, or I
make a mistake in the book. :)
You said you end up with 3 files - .cfs is one of them, right?

Just a quick question: after writing an index and then calling
optimize(), is it normal for the index to expand to about
three times
the size before finally compressing?
In our case the optimise grinds the disk, expanding the index
into
many files of about 145MB total, before compressing down to three
files of about 47MB total. That must be a lot of disk activity
for
the people with multi-gigabyte indexes!

Leto
