Questions to StorageServiceMBean.forceRepaireRangeAsync()

[Lu, Boying]

Hi, All,

We plan to upgrade Cassandra from 2.0.17 to the latest release 2.2.3 in our 
product.

We use:
/**
     * Same as forceRepairAsync, but handles a specified range
     */
public int forceRepairRangeAsync(String beginToken, String endToken, final 
String keyspaceName, boolean isSequential, boolean isLocal, final String... 
columnFamilies);
(defined in StorageServiceMBean.java) to trigger a repair in Cassandra 2.0.17

But this interface is marked as "@Deprecated" in 2.2.3 and has following 
prototype:
@Deprecated
    public int forceRepairRangeAsync(String beginToken, String endToken, String 
keyspaceName, boolean isSequential, boolean isLocal, boolean repairedAt, 
String... columnFamilies);

So my questions are:

1.       If we continue to use this interface, should we set the 'repairedAt' 
to true or false?

2.       If we don't use this interface, which alternative API should we use?

Thanks

Boying
