In Cassandra, I have the following Column Family:
<ColumnFamily CompareWith="TimeUUIDType" Name="Posts"/>
I'm trying to insert a record into it as follows using a C++ generated function generated by Thrift:
ColumnPath new_col;
new_col.__isset.column = true; /* this is required! */
new_col.column_family.assign("Posts");
new_col.super_column.assign("");
new_col.column.assign("1968ec4a-2a73-11df-9aca-00012e27a270");
client.insert("Keyspace1", "somekey", new_col, "Random Value", 1234, ONE);
However, I'm getting the following error: "UUIDs must be exactly 16 bytes"
I've even tried the Cassandra CLI with the following command:
set Keyspace1.Posts['somekey']['1968ec4a-2a73-11df-9aca-00012e27a270'] = 'Random Value'
but I still get the following error:
Exception null
InvalidRequestException(why:UUIDs must be exactly 16 bytes)
