Christian Spriegel commented on CASSANDRA-3370:
-----------------------------------------------
I tried using stress from 1.0.0 and I got the same results as you. Stress for
some reason works fine.
One thing is strange about stress:
I let stress run for quite some time, but there is only 12 MB in the datafolder.
I let my tool run for 10 seconds, but there are 97MB in the data folder.
Is stress maybe not generating random data, so that it compresses really well?
Might that be the difference?
Can I maybe share my application with you? Its a single source file with a
pom.xml.
If you have any idea what I can do, please let me know.
> Deflate Compression corrupts SSTables

> Hi,
> it seems that the Deflate Compressor corrupts the SSTables. 3 out of 3
> Installations were corrupt. Snappy works fine.
> Here is what I did:
> 1. Start a single cassandra node (I was using ByteOrderedPartitioner)
> 2. Write data into cf that uses deflate compression - I think it has to be
> enough data so that the data folder contains some files.
> 3. When I now try to read (I did a range scan) from my application, it fails
> and the logs show corruptions:
> Caused by: org.apache.cassandra.io.compress.CorruptedBlockException:
> (/home/cspriegel/Development/cassandra1/data/Test/Response-h-2-Data.db):
> corruption detected, chunk at 0 of length 65536.
> regards,
> Christian
