Re: Index search in provided list of rows (list of rowKeys).

Not sure it's a feature cassandra needs, it would radically change the meaning of get_indexes_slices(). If you already know the row keys the assumption would be you know they are the rows you want to get. Feel free to add a Jira though. IMHO this sounds more like Sphinx not supporting all the

Configuring multi DC cluster

Hi, Just trying to setup a cluster of 4 nodes for multiDC scenario - with 2 nodes in each DC. This is all on the same box just for testing the configuration aspect. I have configured things as - PropertyFile - 127.0.0.4=SC:rack1 127.0.0.5=SC:rack2 127.0.0.6=AT:rack1 127

The StorageProxyMBean should still be exposed. It won't exist until some reads or writes are performed on the cluster though. You may need to actually do some reads/writes to see it show up. On Tue, Sep 13, 2011 at 11:53 AM, Anand Somani wrote: > Hi, > > Upgraded from 7.4 to 7.8, noticed that St

Hi, Upgraded from 7.4 to 7.8, noticed that StorageProxy (under cassandra.db) is no longer exposed, is that intentional? So the question are these covered somewhere else? Thanks Anand

adding node without bootstrap

If i add node without bootstrap and run repair on both nodes then no data are moved to new node, just new writes are going to new node. This is expected behaviour or it is some kind of user or program error?

Hi, I am in the process of upgrading Cassandra to the recently released v0.8.5 and facing an issue. We had two Cassandra environments - one having 0.7.0 and another 0.7.2. The upgrade on 0.7.2 has happened smoothly, but on the environment having 0.7.0, when I make the switch, the DB fails to come

I ran a repair on 100.5. It returned back almost immediately and netstats and tpstats don't show any additional activity. Nor does the Java process start using more juice. When I look at the cfstats for the main keyspace, number of keys is 0 in all cases. When I look at other nodes in the clust

Trying to do a nodetool cleanup but gets a NullPointerException. I've done some debugging and found out that the property org.apache.cassandra.db.compaction.PrecompactedRow.compactedCf is initilaized to null since ColumnFamilyStore.removeDeleted(ColumnFamily, int) returns null which I interpret as

Can initial_token be decimal or hexadecimal format?

And does it matter when using different partitoners? In the config it seems only strings are used. In RP it parses this string into a BigInteger so it needs to be in decimal format, but for ByteOrderPartitioner it uses FBUtilities.hexToBytes(..) when translating a string to a token (BytesToken).
