So using the code snipped below, I want to create a json representation of
the CF (super).
/**
* Write multiple sub-column values to a super column...
* @param rowKey The key of the row to modify
* @param colFamily The name of the super column family to
operate on
* @param colName The name of the super column
* @param subColumns A list of the sub-columns to write
*/
mutator. writeSubColumns(
userId,
"L1Tickets",
UuidHelper.newTimeUuidBytes(), // using a UUID value that sorts by time
mutator.newColumnList(
mutator.newColumn("category", "videoPhone"),
mutator.newColumn("reportType", "POOR_PICTURE"),
mutator.newColumn("createdDate",
NumberHelper.toBytes(System.currentTimeMillis())),
mutator.newColumn("capture", jpegBytes),
mutator.newColumn("comment") ));
Can someone show me what it would look like?
This is what I have so far....
SupportTickets = {
userId : {
L1Tickets : { }
}
}
But from what I understood, a CF of type super looks like (
http://arin.me/blog/wtf-is-a-supercolumn-cassandra-data-model) :
AddressBook = { // this is a ColumnFamily of type Super
phatduckk: { // this is the key to this row inside the Super CF
// the key here is the name of the owner of the address book
// now we have an infinite # of super columns in this row
// the keys inside the row are the names for the SuperColumns
// each of these SuperColumns is an address book entry
friend1: {street: "8th street", zip: "90210", city: "Beverley
Hills", state: "CA"},
// this is the address book entry for John in phatduckk's address
book
John: {street: "Howard street", zip: "94404", city: "FC", state:
"CA"},
Kim: {street: "X street", zip: "87876", city: "Balls", state: "VA"},
Tod: {street: "Jerry street", zip: "54556", city: "Cartoon", state:
"CO"},
Bob: {street: "Q Blvd", zip: "24252", city: "Nowhere", state: "MN"},
...
// we can have an infinite # of ScuperColumns (aka address book
entries)
}, // end row
ieure: { // this is the key to another row in the Super CF
// all the address book entries for ieure
joey: {street: "A ave", zip: "55485", city: "Hell", state: "NV"},
William: {street: "Armpit Dr", zip: "93301", city: "Bakersfield",
state: "CA"},
},
}
The Pelop's code snippet seems to be adding an additional inner layer to
this to me, confused!
