Hello Experts,

We have column names like, c:vh:1449814025734 in Cassandra. i.e.
c:vh:<timestamp>, after vh timestamp is appended. Is there a way out to read this column using spark connector. Or does spark connector support wildcard where we can fetch columns containing (c:vh:*) or like queries and then we can iterate over it to get our desired value.

Any advice will be of great help.

Thanks!

The Spark Cassandra connector only can read things via the Java Driver so dynamic cell names are not really supported. If the java driver can read them into a (pk, col, val) tuple you could pushdown a predicate on your col but I'm not sure it will.
