Subject Re: Getting serialized Rows from CommitLogSegment file
Date Tue, 02 Oct 2012 13:56:37 GMT
I found a way how to do it, but now I have other issue.

I'm getting a problem when trying to get the ColumnFamily using the CfId.
This information is important to deserialize the stored ColumnFamily.
When I try to use the method Schema.instance.getCF(cfId) to take the
Pair<keyspaceName, columnFamilyName> it throws an
'UnknownColumnFamilyException'.

Seems like the information was dropped or, maybe, not existent in this
instance of the Schema. But, as soon as I know, it's just one instance of
the schema in Cassandra, right?

If I'm mistaking/misunderstanding some structural concept of the Cassandra
here, or if it has other way to take this information, please let me know.

Thanks in advance.
