Issue after dropping a counter column from a table

uuid PRIMARY KEY, A counter, B counter ) . ALTER TABLE keyspace.table DROP A USING TIMESTAMP 1569582510859000; If I do a select in system_schema.dropped_columns, it shows the dropped counter column. How can I properly remove all references to it? Felipe Esteves Tecnologia felipe.este

Re: Huge number of Mismatchs in the logs

Hi, I've got the same problem Upgraded from 2.2.11 to 3.11.3 and since then the DEBUG logs shows this messages. Seems to me that after the repair the messages were reduced a little, but it's still happening. In my case is a 3-node cluster, RF3, reads and writes with LOCAL_QUORUM Felipe Esteves

Re: Migrate from DSE (Datastax) to Apache Cassandra

Ioannis, As some people already said, there's one or two keyspaces that uses EverywhereStrategy, dse_system is one of them, if I'm not wrong. You must remember to change them to a community strategy or it will fail. --

Re: Cassandra seems slow when having many read operations

it high, maybe it will explain the latency in reads. I will try to run a repair on cluster to see how it goes. Felipe Esteves Tecnologia felipe.este...@b2wdigital.com <seu.em...@b2wdigital.com> Tel.: (21) 3504-7162 ramal 57162 Skype: felipe2esteves 2017-07-13 15:02 GMT-03:00 Petru

Cassandra seems slow when having many read operations

instance, row cache is enabled and with almost 100% hit rate. The logs from Cassandra instances doesn't have any errors, nor tombstone messages or something liked that. It's mostly compactions and G1GC operations. Any hints on where to investigate more? Felipe Esteves --

Re: Change authorization from AllowAllAuthorizer to CassandraAuthorizer

Hi, Just a feedback from my scenario, it all went well, no downtime. In my case, I had authentication enabled from the beginning, just needed to change the authorizer. Felipe Esteves Tecnologia felipe.este...@b2wdigital.com <seu.em...@b2wdigital.com> Tel.: (21) 3504-7162 ramal 57162

Change authorization from AllowAllAuthorizer to CassandraAuthorizer

a litte concerned about the performance of the cluster while I'm restarting all the nodes. Is it possible to have any downtime (access errors, maybe), as all the data was created with AllowAllAuthorizer? -- Felipe Esteves Tecnologia felipe.este...@b2wdigital.com <seu.em...@b2wdigital.com>

Nodetool Rebuild sending few big packets of data. Is it normal?

. In the instance logs, I have only stream messages from when I've started the rebuild. My point is, is it normal to Cassandra accumulate this amount of data and then send it? I was hoping that it was more of a gradual and incremental proccess. thanks, Felipe Esteves Tecnologia felipe.este
