It seems that you did not set the AbstractComposite.ComponentEquality.GREATER_THAN_EQUAL to the endComp. You could try something like:

endComp=new Compsite() ;
endComp.addComponent(timeUUID) ;
endComp.addComponent("ACTIVE", StringSerializer.get(), "UTF8Type", AbstractComposite.ComponentEquality.GREATER_THAN_EQUAL) ;

Hope this would help.

This is what I'm trying to do:

Sample of the data:
RowKey: localhost

=> (column=e45549f0-d5b0-11e0-aa6b-005056c00008:INACTIVE, value=<?xml version="1.0" encoding="UTF-8" standalone="yes"?>, timestamp=1315001654327000)

=> (column=e462de80-d5b0-11e0-aa6b-005056c00008:INACTIVE, value=<?xml version="1.0" encoding="UTF-8" standalone="yes"?>, timestamp=1315001654394000)

I'll be activating and deactivating the inactive profiles in a chronological order.

  • So I want to first retrieve current "ACTIVE" record (easy cause it's cached)
  • Put it to use and when ready, recreate the column - same timeUUID but "EXHAUSTED" status (delete then add)
  • Next I have to fetch the first "INACTIVE" column after this, delete that and re-create the record with an "ACTIVE" composite (same timeuuid, again add then delete) and repeat the process.

The second part of my composite is an ENUM of String literals: Status.ACTIVE, Status.INACTIVE, Status.EXHAUSTED

I want to get the current row key of value (startTimeUUID, "ACTIVE") which should only be one column (provided the code works)

All earlier columns are (timeUUID, "EXHAUSTED"), all later columns should be (timeUUID, "INACTIVE")

I'm thinking to find the column that is "ACTIVE" I would set the range:

startComp = new Composite(timeUUID, "ACTIVE");
endComp = new Composite(timeUUID, ""ACTIVE_");

query.setRange(startComp, endComp, false, 2); //Fetch 2 just in case

To get all "INACTIVE" columns I'd use
startComp = new Composite(timeUUID, "INACTIVE");
endComp = new Composite(timeUUID, ""INACTIVE_");

query.setRange(startComp, endComp, false, 10);

Thing is I'm getting back all columns regardless of what I set for the second half of the composite. Is what I'm trying to do possible?
