Subject write timeouts when saving a big object
Date Wed, 22 Apr 2015 07:09:47 GMT
Hi all!

We have a problem with cassandra. We're getting write timeouts when saving
a big object. The object size is approx. 30 Mb which is big but not
enormous as (if I'm not wrong) cassandra can handle up to 2Gb in theory. We
tried increasing write timeout but that didn't help - 10 minutes that we
set were not enough. Maybe there is something wrong with our settings? Our
setup is as follows:

- 4 nodes with cassandra 2.1.3, oracle java 1.7.0_80, 8G xmx (16G of ram
per server)
- replication factor 3

here are pastebin-s with our configs and etc:

effective process command line: http://pastebin.com/FNgcztm0
keyspace and table schema (data is stored in table physicalversiondata,
column data): http://pastebin.com/sWhp4PUk
cassandra.yaml (other config files are left unchanged as per datastax
installation): http://pastebin.com/ZsPRCVJ7

I can provide any other information if required.

Thanks in advance,
Alexander
