Hi,
we came across a question on RIAK's querying ability thru JAVA client.
For example, I have the below JSON record in a RIAK bucket.
I need the individual counts of 'tasks' across different 'statuses'. Like for
the below JSON record, it would be...
- Completed Tasks - 3, InProgress Tasks - 2 and OnHold Tasks -1
What is best way to retrieve this information in Java from RIAK ?
{
"csOutageID" : "110022",
"outageType" : "Value Pack",
"equipmentSerialNumber" : "297912",
"siteName" : "Zhejiang Fuel Gas Power Gen Ltd.",
"technicalCode" : "HD Gas",
"contractNumber" : "CS21753",
"taskCategory" : [{
"taskCategoryId" : "1",
"taskCategoryName" : "TIL",
"taskList" : [{
"taskTaskID" : "1000",
"taskTitle" : "ML 0434
HYDRAULIC SYSTEM SETTING OF THE ACCUMULATOR REFILL RATE",
"taskStatus" : "Complete",
}, {
"taskTaskID" : "1001",
"taskTitle" : "MLI 0104 - HOSE,
CHARGING, ACCUMULATOR",
"taskStatus" : "OnHold",
}]
}, {
"taskCategoryId" : "2",
"taskCategoryName" : "HOTLIST",
"taskList" : [{
"taskTaskID" : "1002",
"taskTitle" : "TEMPERATURE
REGULATION VALVES CONTAINING METHYLENE CHLORIDE",
"taskStatus" : "InProgress",
}, {
"taskTaskID" : "1003",
"taskTitle" : "MSDS Methylene
Chloride to be added in O&M",
"taskStatus" : "Complete",
}]
}, {
"taskCategoryId" : "2",
"taskCategoryName" : "HOTLIST",
"taskList" : [{
"taskTaskID" : "1004",
"taskTitle" : "MIXING
RECOMMENDATIONS FOR SERIES CELLS IN LS2100 AND INNOVATION SERIES STATIC
STARTERS",
"taskStatus" : "InProgress",
}, {
"taskTaskID" : "1005",
"taskTitle" : "BUCKET LOCKWIRE
REDESIGN AND DOWEL PIN ASSEMBLY AND INSPECTION PROCEDURES",
"taskStatus" : "Complete",
}]
}]
}
Thanks & regards,
Prem
