AggregationClient.avg(byte[] tableName,
ColumnInterpreter<R,S> ci,
Scan scan)
This is the client side interface/handle for calling the average method for a given cf-cq combination. |
|
|
AggregationClient.max(byte[] tableName,
ColumnInterpreter<R,S> ci,
Scan scan)
It gives the maximum value of a column for a given column family for the given range. |
|
|
AggregationClient.min(byte[] tableName,
ColumnInterpreter<R,S> ci,
Scan scan)
It gives the minimum value of a column for a given column family for the given range. |
|
|
AggregationClient.rowCount(byte[] tableName,
ColumnInterpreter<R,S> ci,
Scan scan)
It gives the row count, by summing up the individual results obtained from regions. |
|
|
AggregationClient.std(byte[] tableName,
ColumnInterpreter<R,S> ci,
Scan scan)
This is the client side interface/handle for calling the std method for a given cf-cq combination. |
|
|
AggregationClient.sum(byte[] tableName,
ColumnInterpreter<R,S> ci,
Scan scan)
It sums up the value returned from various regions. |
