Deserialization of java runtime serialized objects has been identified as a security risk (CVE-2023-36480) by CodeQL team members @atorralba (Tony Torralba) and @joefarebrother (Joseph Farebrother). See Incompatible API change.

• CLIENT-2455 Default Value.UseBoolBin to true. If true, the boolean (instead of integer) data type will be used on writes of boolean bins. See Incompatible API change

• CLIENT-2304 Add Exp.inf() and Exp.wildcard().

• CLIENT-2324 Support packing of Short, Byte, Character, Enum and UUID entries in list/map. Enum and UUID are packed as strings.

Fixes

• CLIENT-2244 Deprecate Map Bin constructor with extra MapOrder argument.

• CLIENT-2181 Add TestMapExp sortedMapEquality() test.

Fixes

• Upgrade netty version to 4.1.89.Final.

• Update listener docs. Remove mention of batch termination on exception in batch listener onRecord() docs because parallel batch node commands will still run to completion. Distinguish between batch behavior and scan/query behavior on onRecord() exception in RecordSequenceListener.

• Document potential issue when using paginated queries and not iterating through all records in the RecordSet. Emphasize that PartitionFilter.after() does not work for a secondary index query.

• Change TestIndex.createDrop() to ensure all nodes have dropped the index using direct info commands.

• Change QueryPolicy.shortQuery doc to say "less than 100 records per node".

Features

Fixes

• CLIENT-1951 Consider all replicas when retrying a foreground scan/query after a partition unavailable error.

• CLIENT-1996 Return Long instance when parsing an integer particle type even if integer byte length is not equal to 8. Currently, the server always returns length 8 for integer particle types.

• CLIENT-2002 Check for error in info command response string when parsing racks and partitions.

• CLIENT-2003 Handle "java.lang.Short" as a numeric Value. Also, add "Bin(String name, short value)" constructor and "Value.get(short)".

Fixes

• CLIENT-1813 Handle background and aggregation queries with set names that do not exist on server nodes. The client now terminates a background/aggregation query when the server returns KEY_NOT_FOUND_ERROR on non-existent sets. Previous versions would timeout by default because the client was waiting for the INFO3_LAST bit to be set, which is not returned by the server.

• Prevent division by zero if the node array is empty in getRandomNode().

• Add Filter colType and packedCtx fields to equals() and hashCode().

• Update default values in run_benchmark usage.

• Align Value factory method with the primitive char.

Features

• CLIENT-1805 Add "Value.ReturnMapForKeyValue" boolean. If true, the client will always return a map when "MapReturnType.KEY_VALUE" is specified in a map read operation and the server returns a list of key/value pairs. The default is false.

Fixes

• Remove check for 0x04 map extension bit in unpackMap() because the server never sends it.

• Remove link to non-existent screenshot in examples readme.

• CLIENT-1759 Set correct batch read operation attribute for operations that do not include a bin name (ie Operation.get()).

• CLIENT-1768 Allow read all bins operation (Operation.get()) to be used in batch operations. Disable respondAllOps policy when read all bins operation is used.

• CLIENT-1767 Set scan/query iteration on each scan/query node sub-exception. The sub-exceptions are then displayed in the final scan/query exception message.

• Do not obfuscate aggregation query errors when client side lua packages fail to load.

Fixes

• CLIENT-1637 Continue processing scans when "partition unavailable" errors occur. "partition unavailable" is not a fatal error for partition scans and the server will continue sending back results for other partitions. Previous clients aborted the scan and put the connection back into the pool which might cause unprocessed results to be sent to a different transaction.

• CLIENT-1537 Use separate boolean to indicate cluster is closed instead of setting commands "pending" integer to a fixed value.

• CLIENT-1537 Add "try/catch" blocks around async code that cannot fail. Log a message and stacktrace with a Level of ERROR if an exception is caught in this critical code.

• CLIENT-1537 Align EventLoop "pending" (pending for entire eventloop) with EventState "pending" (pending for each cluster within an eventloop) so modifications occur at the same time.

• CLIENT-1537 Change async connection recovery to not modify "pending". Connection recovery is now independent of "pending" limits and accounting.

• CLIENT-1537 Increment node error count on server timeouts.

• A bug affecting this version of the Java client has been identified. If your application uses scans, we strongly recommend that you upgrade to Java client 5.1.11 at the earliest opportunity.

Fixes

• Fix equals() in BoolIntValue to cast other to BoolIntValue instead of BooleanValue.

• A bug affecting this version of the Java client has been identified. If your application uses scans, we strongly recommend that you upgrade to Java client 5.1.11 at the earliest opportunity.

Features

• CLIENT-1461 Support boolean particle type. If "Value.UseBoolBin" is true, a boolean is sent to the server as a boolean bin instead of an integer bin. Server version 5.6+ is required when "Value.UseBoolBin" is true. Default is false.

• CLIENT-1475 Support new math, bit, and conditional expressions. These expressions require server version 5.6+.

• CLIENT-1486 Support user quotas and statistics. This feature requires server version 5.6+.

• CLIENT-1501 Remove Policy.priority, ScanPolicy.scanPercent and ScanPolicy.failOnClusterChange. The server no longer supports these fields. See Incompatible API change.

• CLIENT-1511 Support TCP keep-alive when using netty-transport-native-epoll library. When keep-alive detects an invalid socket in a connection pool, an event is sent that is used to close that socket and remove it from the connection pool.

• Support UUID value type.

Fixes

• Do not keep connection on all client side errors.

• A bug affecting this version of the Java client has been identified. If your application uses scans, but does not use Policy.priority , ScanPolicy.scanPercent or ScanPolicy.failOnClusterChange, you can safely upgrade to Java client 5.1.11. We strongly recommend that you do so at the earliest opportunity.

Fixes

• CLIENT-1493 Check for timeout in all netty callbacks.

• CLIENT-1493 Catch netty connection close exceptions.

• CLIENT-1493 If connection pool is full, abort connection balance for that iteration.

• CLIENT-1493 Decrement connection total when AsyncConnector fails before AsyncConnection is instantiated.

• CLIENT-1494 Detect quick node restart when restarted node never left the cluster. If detected, reset error count and balance connections.

• A bug affecting this version of the Java client has been identified. If your application uses scans, but does not use Policy.priority , ScanPolicy.scanPercent or ScanPolicy.failOnClusterChange, you can safely upgrade to Java client 5.1.11. We strongly recommend that you do so at the earliest opportunity.

Features

• CLIENT-1473 Accept new boolean particle type on reads, but continue writing boolean as an integer bin. This is an interim step that allows rolling upgrades with boolean support when server version 5.6 is released.

• CLIENT-1482 Add Node getPeersGeneration(), getPartitionGeneration() and getRebalanceGeneration().

• CLIENT-1487 Remove ability to use old authentication protocol since the new authentication protocol was created in server version 4.1 and this client already requires server version 4.9+.

• Implement more accurate ClusterStats by collecting async data directly in event loop threads.

• Support enums in Value.get().

Fixes

• CLIENT-1488 Reserve async connection slots in advance for AsyncConnector. This should prevent a node's async connection count from exceeding asyncMaxConnsPerNode.

• CLIENT-1485 Remove ability to configure password hash as the password when using authentication.

• Fix potential null pointer exception in QueryAggregateCommand.

• Convert preceding spaces to tabs.

• Do not run tests on enterprise features when using community edition.

• Avoid deprecation warnings when using netty and junit.

• A bug affecting this version of the Java client has been identified. If your application uses scans, but does not use Policy.priority , ScanPolicy.scanPercent or ScanPolicy.failOnClusterChange, you can safely upgrade to Java client 5.1.11. We strongly recommend that you do so at the earliest opportunity.

Features

• CLIENT-1407 Support optional connectTimeout policy. If connectTimeout greater than zero, it will be applied to creating a connection plus optional user authentication.

• CLIENT-1430 Allow async command argument eventLoop to be null. If null, round-robin event loop distribution (eventLoops.next()) is used to set eventLoop.

• Start HashWheeledTimer as soon as async event loop starts running.

Fixes

• CLIENT-1391 Reset peers, partition and rebalance generations on node tend errors. This forces a client node refresh when a node is quickly restarted with the same generation, but with different peers, partition maps or rack nodes.

• Check for null value in Record.getGeoJSONString().

• Deprecate Record.getGeoJSON(). Use Record.getGeoJSONString() instead.

• Use non-atomic increment in async examples/tests when counter is only modified by a single event loop thread.

• A bug affecting this version of the Java client has been identified. If your application uses scans, but does not use Policy.priority , ScanPolicy.scanPercent or ScanPolicy.failOnClusterChange, you can safely upgrade to Java client 5.1.11. We strongly recommend that you do so at the earliest opportunity.

Features

• CLIENT-1377 Reject command when assigned node's error rate exceeds ClientPolicy.maxErrorRate per ClientPolicy.errorRateWindow. The node's error count is incremented on any error that causes the connection to close (socket errors and client timeouts) plus ResultCode.DEVICE_OVERLOAD. Attempt retry before throwing AerospikeException.Backoff. Default maxErrorRate (0) disables error rate rejection.

• Retry on ResultCode.DEVICE_OVERLOAD.

• CLIENT-1375 Add Expression.getBase64() to return base64 encoded string of packed expression bytes.

• CLIENT-1378 Add setXDRFilter().

• Add ResultCode.LOST_CONFLICT.

If your application uses scans, but does not use Policy.priority , ScanPolicy.scanPercent or ScanPolicy.failOnClusterChange, you can safely upgrade to Java client 5.1.11. We strongly recommend that you do so at the earliest opportunity.
• Requires server version 4.9+.

Features

• CLIENT-1373 Retrofit support for old PredExp in addition to new Expressions. Both expression filters will be supported for 1 year in order to ease the transition to new Expression APIs. After that, PredExp support will be permanently removed. Also, support server version 4.9+ instead of the more strict 5.2.0.4+ requirement. Expression API usage still requires server 5.2.0.4+.

• Add Exp.memorySize(). This method requires server version 5.3+.

Fixes

• Remove extraneous newline in ClusterStats toString().

• Add exp package to javadocs.

• A bug affecting this version of the Java client has been identified. If your application uses scans, but does not use Policy.priority , ScanPolicy.scanPercent or ScanPolicy.failOnClusterChange, you can safely upgrade to Java client 5.1.11. We strongly recommend that you do so at the earliest opportunity.
• Requires server version 5.2.0.4+. It's not recommended to use this client version since client 5.0.1 has more relaxed server version requirements.

Features

• CLIENT-1359 Replace PredExp with new Expressions. Expression filters give access to the full data type APIs (List, Map, Bit, HyperLogLog, Geospatial) and expanded metadata based filtering, to increase the power of filters in selecting records. This client requires server version 5.2.0.4+. See Incompatible API change.

• CLIENT-1369 Remove legacy client code for old servers since this client now requires server version 5.2.0.4+.

• CLIENT-1181 Add Log.setCallbackStandard().

• Add hashCode() and equals() to Policy and WritePolicy.

Fixes

• CLIENT-1356 Wait until seed node is fully validated before creating minimum connections.

• CLIENT-1358 Expand recoverable connections scope to include async netty commands in connect state.

Fixes

• CLIENT-2513 Return java serialized blobs as raw byte[] instead of throwing an exception. See Incompatible API change.

Fixes

• CLIENT-2252 Disable java runtime serialization/deserialization. Deserialization of java runtime serialized objects has been identified as a security risk (CVE-2023-36480) by CodeQL team members @atorralba (Tony Torralba) and @joefarebrother (Joseph Farebrother). See Incompatible API change.

Fixes

• CLIENT-1637 Continue processing scans when "partition unavailable" errors occur. "partition unavailable" is not a fatal error for partition scans and the server will continue sending back results for other partitions. Previous clients aborted the scan and put the connection back into the pool which might cause unprocessed results to be sent to a different transaction.

• A bug affecting this version of the Java client has been identified.
  • If your application uses scans, we strongly recommend that you upgrade to Java client 4.4.20 at the earliest opportunity.

New Features

• A bug affecting this version of the Java client has been identified.
  • If your application uses scans, we strongly recommend that you upgrade to Java client 4.4.20 at the earliest opportunity.

Bug Fixes

• CLIENT-1310 Allow ScanPolicy scanPercent to be sent for server versions >= 4.9 when scanPercent is changed from the default. Also, throw an exception if both scanPercent and maxRecords are changed from the default. scanPercent/maxRecords are mutually exclusive.
• CLIENT-1336 Fail immediately with detailed message when a seed connection error occurs and seed host tlsName defined, but client tlsPolicy is not defined.
• Fix errors/warnings generated by newer versions of javadoc.

• A bug affecting this version of the Java client has been identified.
  • If your application uses scans, we strongly recommend that you upgrade to Java client 4.4.20 at the earliest opportunity.

  • If your application uses scans, we strongly recommend that you upgrade to Java client 4.4.20 at the earliest opportunity.

New Features

• CLIENT-1291 Allow maxSocketIdle to be set to zero (no reap). Connections retrieved from pools in transaction threads will not be checked for maxSocketIdle when maxSocketIdle is zero. Idle connections will still be trimmed down from peak connections to min connections in the cluster tend thread using a hard-coded 55 second limit when maxSocketIdle is zero.
• CLIENT-1287 If a batch request to a node fails, continue processing other node responses for async batch read methods that accept a sequence listener (ExistsSequenceListener, BatchSequenceListener, RecordSequenceListener).
• Add AerospikeClient getCluster().
• Add ExecuteTask getTaskId().
• Add create nested map and create nested list examples.

Bug Fixes

Fixes

• CLIENT-934 Direct NIO async socket reads fail when socket buffer size greater than ByteBuffer capacity. Fix by setting ByteBuffer limit to socket buffer receive size whenever a new ByteBuffer needs to be created.

• CLIENT-933 Client does not always revert to seeds when entire cluster is unreachable. Fix by reverting to seeds after all node info requests fail 5 consecutive times (5 seconds) regardless of cluster size.

• Add copy constructors for policy classes that did not have them.

• Add null check for exceptions in Cluster::seedNodes(). Thanks to Kenneth Jorgensen for the fix.

Features

• CLIENT-919 Support user configurable ThreadLocalData.DefaultBufferSize

• Support QueryPolicy.includeBinData

Fixes

• Always check for maxRetries regardless of totalTimeout setting.

• Distinguish between client and server timeout in exception message.

Fixes

• Fix null pointer exception in async commands when connection fails, a retry occurs, and the socket idle timeout is in effect.

• Retry async commands by placing commands at the end of the queue so other async commands have a chance to run.

Fixes

• Treat socketTimeout as a socket idle timeout when processing both sync and async commands.

• Fix async direct NIO command where socket read event was not registered after partial socket write completed.

Fixes

• Fix null pointer exception on synchronous batch, scan, query commands when a retry occurs.

Fixes

• Decrement async connection count by calling closeAsyncConnection() instead of socket close() directly when connection validation fails.

Fixes

• Remove waitTillComplete() and notifyComplete() in async examples because most async applications should not use these synchronization methods. Async examples will now run in parallel, so the log message order will be mixed.

• Only set "peers.genChanged" to true when peers protocol is supported by the server.

• Disallow GeoJSON type as a key.

• Handle polling tasks with a timeout the same way as a no-timeout task.

• On AerospikeClient close(), return before actual shutdown if called from an event loop thread. This is done to prevent deadlock.

Features

• Support Netty Epoll event loops (EpollEventLoopGroup) on Linux based operating systems.

Fixes

• Fix Connection.IsClosed() bug (introduced in 4.0.0) by restoring lastUsed timestamp on connect. Cluster tend connections will now stay open between tend intervals.

Features

• Complete async rewrite. AerospikeClient now supports both async and sync methods. Async methods can use either Netty or direct NIO event loops.Async methods also allow the target event loop to be specified. Benchmarks and examples have been modified to use the new async methods.

• The old AsyncClient is still supported, but has been marked obsolete. The async methods in AerospikeClient perform significantly faster than the old AsyncClient, so it's recommended to port your async applications to use the new AerospikeClient async methods.

• See Async Documentation.

• Split Policy timeout into socketTimeout and totalTimeout.

• Changed Policy replica default to Replica.SEQUENCE.

• Changed Policy maxRetries default to 2.

• See Incompatible API change for more details on Policy changes.

Fixes

• CLIENT-891 Propagate batch read consistencyLevel to sub-transactions.

• AER-5650 Fixed PredExp.geoJSONValue().

• Enforce maxConnsPerNode as a hard limit. Return new result code NO_MORE_CONNECTIONS if this limit would be exceeded.

• Use separate connection for tend thread to guarantee a tend connection.

• Support new async policy timeoutDelay which delays closing of connection if a timeout occurred. The delay may allow the transaction to finish so the socket can be reused. The user is still notified immediately of the timeout and the delayed response is discarded.

• Validate async connections using non-blocking read of 1 byte.

• Retry async connections in connection pool until a valid connection is found or pool is exhausted.

• Remove all other async retries.

• Reduce result codes that require closing of socket.

• CLIENT-650 Generate scan/query task ids using RandomShift instead of nano time.

• Enforce server's single query filter constraint on client.

• Always run asynchronous authentication status check in selector thread (never offload to another thread).

• Send original key (with namespace/set) back to sequence listeners in asynchronous batch.

Features

• Support new batch index protocol which allows multiple namespaces, bin name filters, and read types (read, exists) to be specified in a single batch call.

• Added new LargeList methods which are supported by Aerospike server versions >= 3.5.8.

• Replaced configuration userModule/createModule with LargeList.setPageSize().

• Removed unnecessary LargeList getCapacity() and setCapacity().

Fixes

• Fixed a bug with Value.equals().

• Read resource files using resource stream instead of File.

Features

• Support reading User-Defined Functions (UDFs) from resources.
