Uses of DataIterator in com.gigaspaces.datasource

Methods in com.gigaspaces.datasource that return DataIterator

DataIterator<Object>	SpaceDataSource.getDataIterator(DataSourceQuery query) This method is invoked whenever the space needs to read data which matches the provided DataSourceQuery from the space data source.
DataIterator<Object>	SpaceDataSource.getDataIteratorByIds(com.gigaspaces.datasource.DataSourceIdsQuery idsQuery) This method is invoked whenever the space needs to read several entries from the data source according to their ids.

Uses of DataIterator in org.openspaces.persistency.cassandra.datasource

Classes in org.openspaces.persistency.cassandra.datasource that implement DataIterator

class	CassandraTokenRangeAwareDataIterator
class	CassandraTokenRangeAwareInitialLoadDataIterator
class	CassandraTokenRangeJDBCDataIterator Note: the underlying cassandra jdbc implementation brings the entire batch when calling execute, so SQLException exceptions will actually only be thrown during prepare statement and execute statment Moreover, the iteration over the results is currently only logical because the entire result set already lies in memory after execute statement returns.
class	SingleEntryDataIterator A DataIterator for single entry or empty result sets.
