sorry,i find igniteClient.compute() has no affinityCallAsync method ,does
igniteClient can call affinityCallAsync

Subject: Re: count cache key number
There are a number of ways to tackle this.
If your cache split the key into distinct fields rather that a concatenated
string, you could SQL-enable your cache and get your count as a simple SELECT
statement.
Alternatively, there’s an affinity compute task that takes a partition
(affinityCallAsync). If you use that and a ScanQuery that fetches records from
a specific partition (ScanQuery), you’ll get something like a map-reduce. (You
could also use the map-reduce API, but an affinity call is probably easier.)

hi
do I pass cache in distribute compute than use cache scan ,that faster than I
use a cache scan in client api.

Subject: count cache key number
Hi,
I have a cache ,it's key like
"mobile:140000"
"mobile:140001",
"address:test1",
"address:test2",
"address:test3"。
I want to count mobile number and address number。
address number is 3 and mobile number is 2。I see Ignite doc has mapreduce
job，but it seem not example iterator cache key。 is there any method to iterator
key in mapreduce job。Thank you very much
