I'm new to cassandra, and I want use it to store:
loggers = { // (super)ColumnFamily ?
logger1 : { // row inside super CF ?
timestamp1 : {
value : 10
},
timestamp2 : {
value : 12
}
(many many many more)
}
logger2 : { //logger of diffrent type (in this example it logs 3 values
instead of 1)
timestamp1 : {
v : 300,
c : 123,
s : 12.13
},
timestamp2 : {
v : 300
c : 123
s : 12.13
}
(many many many more)
}
(many many many more)
}
the only way i will be accesing this data is:
- example: fetch slice of data from logger2 ( start = 1278009131 (timestmap)
, end = 1278109131 )
expecting sorted array of data.
- example: fetch slice of data from (logger2 and logger10 and logger20 and
logger1234) ( start = 1278009131 (timestmap) , end = 1278109131 )
expecting map of sorted arrays of data. [it is basically N queries of
first type]
is this right definition of above: <ColumnFamily CompareWith="TimeUUIDType"
ColumnType="Super"
CompareSubcolumnsWith="BytesType" Name="loggers"/> ?
what's the best way to model this data in cassadra (keeping in mind
partitioning and other important stuff) ?
