This is a shot into the dark but you could check whether you have too many
snapshots laying around that you actually don't need. You can get rid of
those with a quick nodetool clearsnapshot.

In the past in such scenarios it has helped us to check the partition where
cassandra is installed and allocate more space for the partition. Maybe it is a
disk space issue but it is good to check if it is related to the space
allocation for the partition issue. My 2 cents.

my 2 cents:
try major compaction on the column family with TTL's - for sure will be
faster than full rebuild.
also try not cassandra related things, such check and remove old log files,
backups etc.

Hi,
I am trying to benchmark our custom schema in Cassandra and I managed to
run it. However there are couple of setting and issues which I couldn't
find any solution/explanation for. I appreciate any comments.

Major compaction is bad if you're using size-tiered, especially if you're
already having capacity issues. Once you have one huge table, with default
settings, you'll need 4x that huge table worth of storage in order for it
to compact again to ever reclaim your TTL'd data.
If you're running into

I deploy/distribute the Cassandra database as an embedded service allowing me
to create a basic cassandra.yaml file based on the global cluster of machines
(seeds, non-seeds, ports, disks, etc...). That allows me to configure and
upgrade my own software and the cassandra software using the same
thanks for the answers!

Hi All,
Has anyone done any performance testing of say Cassandra 2.1 using Java 8?
Thanks,-Tony
If you only run incremental repairs, does that mean that bitrot will go
undetected for already repaired sstables?
If so, is there any other process that will detect bitrot for all the repaired
sstables other than full repair (or an unfortunate user)?

Compressed SSTables store a checksum for every compressed block, which is
checked each time the block is decompressed. I believe there's a ticket
out there to add something similar for non-compressed SSTables.
We also store the sha1 hash of SSTables in its own file on disk.

Not a direct answer to your post but you can also take a look at YCSB.
