Re: Suggestions for migrating data from cassandra

2018-05-15 Thread Michael Dykman
I don't know that there are any projects out there addressing this but I advise you to study LOAD ... INFILE in the MySQL manual specific to your target version. It basically describes a CSV format, where a given file represents a subset of data for a specific table. It is far and away the fastest

Documentation of batch statements

2015-03-03 Thread Michael Dykman
While the above statement may be strictly true, it is misleading. A more accurate statement would be "...if any of the batch FAILS, all of it will." As originally written, a naive reader might assume that atomicity pivots on success; the point of atomicity is reliable failure. -

Re: Can not connect with cqlsh to something different than localhost

2014-12-07 Thread Michael Dykman
Try: $ netstat -lnt and see which interface port 9042 is listening on. You will likely need to update cassandra.yaml to change the interface. By default, Cassandra is listening on localhost so your local cqlsh session works. On Sun, 7 Dec 2014 23:44 Richard Snowden wrote: > I am running Cassandr

I wonder; your jar creation looks a little off and I suspect your problem might be the jar format which would lead to the failure to load. Could you list the output of $ unzip -l my.jar? On Jul 28, 2014 3:49 AM, "Martin Marinov" wrote: > I did: > ls /etc/cassandra/triggers/ > InvertedIndex.jar
