方法详细资料

open

void open()
   throws Exception

open the resources of the Context, this method should first call before call other methods.

抛出:

Exception

getPartition

Optional<P> getPartition(List<String> partValues)
                  throws Exception

Get partition by file partition values.

抛出:

Exception

getComparablePartitionValueList

List<PartitionFetcher.Context.ComparablePartitionValue> getComparablePartitionValueList()
                                                                                 throws Exception

Get list that contains partition with comparable object.

For 'create-time' and 'partition-time',the comparable object type is Long which represents time in milliseconds, for 'partition-name', the comparable object type is String which represents the partition names string.

抛出:

Exception

close

void close()
    throws Exception

close the resources of the Context, this method should call when the context do not need any more.
