You can also stop repair using JMX without restarting. There are scripts to do that. Hannu > On 6 Jul 2017, at 23.24, ­Fay Hou [Storage Service] > wrote: > > There is a bug on repair system_auth keyspace. We just skip the repair on > system_auth. Yes. it is ok to kill

I have started a repair on my system_auth keyspace. The repair has started and the process shows as running with ps but am not seeing any CPU with top. I’m also note seeing any antientropy sessions building merkle trees in the log. Can I safely kill a repair and how? Mark Furlong Sr.

You can set timeout value in cqlshrc file. But you will have to overload the cluster to take these into effect. Sent from my iPhone > On Jul 6, 2017, at 10:08 AM, Charulata Sharma (charshar) > wrote: > > Hi All, > > Recently I learnt that in C* driver versions

Simulating Read and WriteTimeouts programatically

Hi All, Recently I learnt that in C* driver versions 3.1.x and up, there is a change in retry. If the query statement is not idempotent, there won't be any retry and by default the queries are considered to be non idempotent. Hence, even though Retry policy is mentioned while setting up the C*

Cassandra uses the writetime to resolve the conflict. Highest time stamp wins. There's no guarantee on the order the mutations arrive in. On Thu, Jul 6, 2017 at 7:14 AM suraj pasuparthy wrote: > thanks Pranay, > But is the order maintained across tables? > As in the

thanks Pranay, But is the order maintained across tables? As in the client in DC1 first writes record A in table A and then immediately writes Record B in Table B, So will the order be maintained, where in Table A gets synced first and then Table B? Thanks again -Suraj On Wed, Jul 5, 2017 at
