how to load schema file into Cassandra with cqlsh

问题:

I have a schema file for Cassandra. I'm using a windows 7 machine (Cassandra on this machien as well - 1 node). I want to load the schema with cqssh. So far I have not been able to find how. I was hoping to be able to pass the file to cqlsh: cqlsh mySchemaFile. However since I run in windows, to start cqlsh I do the following

python "C:\Program Files (x86)\DataStax Community\apache-cassandra\bin\cqlsh" localhost 9160

Even though I have csqsh in my path, when called like this from python it needs the full path.

I tried to add in there the file name but no luck so far. Is this even possible?

回答1:

cqlsh takes a file to execute via the -f or --file option, not as a positional argument (like the host and port), so the correct form would be:

python "C:\Program Files (x86)\DataStax Community\apache-cassandra\bin\cqlsh" localhost 9160 -f mySchemaFile

Note: I'm not 100% sure about whether you'd use -f or \f in Windows.
