Package org.apache.accumulo.core.client

Interface Summary

Interface	Description
BatchDeleter	Implementations of BatchDeleter support efficient deletion of ranges in accumulo.
BatchScanner	In exchange for possibly returning scanned entries out of order, BatchScanner implementations may scan an Accumulo table more efficiently by Looking up multiple ranges in parallel.
BatchWriter	Send Mutations to a single Table in Accumulo.
ConditionalWriter	ConditionalWriter provides the ability to do efficient, atomic read-modify-write operations on rows.
Instance	This class represents the information a client needs to know to connect to an instance of accumulo.
MultiTableBatchWriter	This class enables efficient batch writing to multiple tables.
Scanner	Scans a table over a given range.
ScannerBase	This class hosts configuration methods that are shared between different types of scanners.

Class Summary

Class	Description
BatchWriterConfig	This object holds configuration settings used to instantiate a BatchWriter
ClientConfiguration	Contains a list of property keys recognized by the Accumulo client and convenience methods for setting them.
ClientSideIteratorScanner	A scanner that instantiates iterators on the client side instead of on the tablet server.
ConditionalWriter.Result
ConditionalWriterConfig
Connector	Connector connects to an Accumulo instance and allows the user to request readers and writers for the instance as well as various objects that permit administrative operations.
IsolatedScanner	A scanner that presents a row isolated view of an accumulo table.
IsolatedScanner.MemoryRowBuffer
IsolatedScanner.MemoryRowBufferFactory
IteratorSetting	Configure an iterator for minc, majc, and/or scan.
IteratorSetting.Column	A convenience class for passing column family and column qualifiers to iterator configuration methods.
RowIterator	Group Key/Value pairs into Iterators over rows.
ZooKeeperInstance	An implementation of instance that looks in zookeeper to find information needed to connect to an instance of accumulo.
