What can you set into a dataSet

you can see skeleton of dataset here :

• Xml dataSet skeleton
• JSON dataSet skeleton
• Yaml dataSet skeleton

A lot of elements are optionals and work with default value. Here is a description of theses elements : ##1. keyspace level :

• name : the name of the keyspace to create
• strategy (optional) : the strategy of the keyspace to choose between
  • "org.apache.cassandra.locator.LocalStrategy" (as default)
  • "org.apache.cassandra.locator.NetworkTopologyStrategy"
  • "org.apache.cassandra.locator.SimpleStrategy"
• replicationFactor (optional) : the replication factor of the data in the keyspace. "1" as default.
• columnFamily : a list of column family.

##2. columnFamily level :

• name : the name of the Column Family
• type (optional) : the type of the Column Family to choose between :
  • "STANDARD" (as default)
  • "SUPER"
• keyType (optional) : The Data Type of the key to choose between :
  • "BytesType" (as default)
  • "IntegerType"
  • "LexicalUUIDType"
  • "LongType"
  • "TimeUUIDType"
  • "UTF8Type"
  • "UUIDType"
• comparatorType (optional) : The Data Type of the Column name to choose between :
  • "BytesType" (as default)
  • "IntegerType"
  • "LexicalUUIDType"
  • "LongType"
  • "TimeUUIDType"
  • "UTF8Type"
  • "UUIDType"
• subComparatorType (optional) : Not taken into account if your Column Family type is "STANDARD". The Data Type of the Sub Column name to choose between :
  • "BytesType" (as default)
  • "IntegerType"
  • "LexicalUUIDType"
  • "LongType"
  • "TimeUUIDType"
  • "UTF8Type"
  • "UUIDType"
• defaultColumnValueType (optional) : The Data Type of all Column value to choose between :
  • "BytesType" (as default)
  • "IntegerType"
  • "LexicalUUIDType"
  • "LongType"
  • "TimeUUIDType"
  • "UTF8Type"
  • "UUIDType"
  • "CounterColumnType" (to define the column family as a counter column family) Since the version 0.8.0.4

(If you want to set different yype into column value, ou can use "Function for value" which is explained below.)

• columnMetadata (optional) : a list of column metadata Since the version 1.0.1.2
• row (optional) : a list of row

##3. colummMetadata level

• name : the name of the column
• validationClass : the validationClass of the column value to choose between :
  • "BytesType" (as default)
  • "IntegerType"
  • "LexicalUUIDType"
  • "LongType"
  • "TimeUUIDType"
  • "UTF8Type"
  • "UUIDType"
• indexType (optional) : define if the column is indexed. Possible value are :
  • "KEYS"

##4. row level

• key : the key value of the row
• column (optional) : a list of column
• superColumn (optional) : a list of superColumn. Not taken into account if your Column Family type is "STANDARD".

##5. superColumn level

• name : the name of the super column
• column (optional) : a list of column

##6. column level

• name : the name of the column
• value (optional): the value of the column.

If the "defaultColumnValueType" element is set at the column Family level, the value has to be a valid regarding to the type. If not set, the value has to be a valid hexByte because the default type is "BytesType".
