High Availability• Support for "Consistent hashing" data partitioning for shards

As the data architect of a sharded cluster application, I need a way to make adding and removing nodes (computers) to the Informix cluster faster. Currently, we are using a hashing scheme to distribute data across the nodes. When we add or remove a node, most of the data gets moved, either to the new node or between existing nodes. We need a mechanism to distribute our data across our sharded cluster without moving all the data whenever we add or remove a node.

• Redesigned parallel CHECK REPAIR

Users can see deadlocks and 'repair jobs' being aborted while running parallel ‘CHECK REPAIR' jobs.

• Add constraint name to ATS/RIS files when they are generated due to foreign key constraint issues

Reduce time spent in diagnosing problems related to aborted transactions. If transactions are aborted due to referential constraint failures while replaying transactions at ER target server, it will be much easier to identify the issue with the associated constraint name.

SQL• BSON_UPDATE function

Updates that you make to JSON documents now run faster because they are run in the database server instead of in the wire listener.

When you run the BSON_UPDATE function in an SQL statement, you can now include the MongoDB array update operators.

• COALESCE function

Customers can now evaluate a series of expressions to return the first non-null value by running the COALESCE function.

• NOVALIDATE option for check constraints

The NOVALIDATE keyword prevents the database server from checking every row for referential integrity during ALTER TABLE ADD CONSTRAINT and SET CONSTRAINTS operations on foreign-key constraints.

Extensibility• Spatio Temporal Search

As a developer, we are building an application that tracks movement of various mobile sensors over time. We need to be able to query past and present locations and values for each sensor, as well as establish geo-fence boundaries for these sensors with immediate feedback when the boundary conditions have been crossed.

Extensibility• TimeSeries Pattern Matching

As a developer, we are developing analytic functions to examine the sensor data in our application. Many of the mechanical components for which we are collecting timeseries data have well defined patterns that reflect wear, and thus impending failure. We’d like to be able to provide an algorithmic representation of this pattern and have the database engine determine whether the wear condition is present when loading the timeseries data.

• Rolling Window for Sub-second (Hertz) TimeSeries

As a DBA, we have an application that records sensor data 50 times per second for thousands of devices. We have a requirement to keep one week’s worth of data online, but want to archive data as it gets older than one week. Managing the space requirements for this table is difficult as there is no way to automatically detach the storage for this type of data as it reaches the specified age. With the massive amounts of data that we have to manage, we need the database to enable and disable pre-allocated storage containers (fragments) for this regular frequency (Hertz) timeseries data.

• Spatial support for GeoJSON

Support to display spatial data in JSON-based applications by converting a geometry to a BSON document in GeoJSON format.

Internet of Things (IoT)• MQTT Listener

As an IoT application developer, I want to be able to send sensor data directly to the database. As a widely accepted standard in the IoT space, all my sensors have the ability to publish readings via MQTT protocol. I would like to have my Informix database be able to ingest this sensor data directly from the sensors, without the need for an external MQTT broker.

Internet of Things (IoT)• Informix to Spark Streaming Prototype

As a developer, I need to perform distributed stream processing and advanced analytics on my transactional data to gain real time insight for my business. Instead of batch processing, I need to stream the transactional data to a stream processing engine without disrupting or adding complexity to my transactional data which drives my business. I need a way for my operational (relational/NoSQL) database to stream the transactional data to an external distributed stream processing engine through a well-known/universally supported protocol like MQTT.

Wire Listener• Mongo 3.2 API Support

As a developer, we need to use the latest version of MongoDB’s various programming language drivers (JDBC, Python, node.js, etc), in order to ensure the latest security and functionality enhancements for our customers. In order to continue to be able to run our hybrid applications with Informix as well, we must be able to use the same MongoDB 3.2 drivers with Informix.

• TimeSeries Aggregation Queries

Support for aggregations using the TimeSeries AggregateBy function. In the Mongo aggregation framework this is done with a $group by a $calendar object. The supported aggregation operators for timeseries data will be: $sum, $avg, $min, $max, $median, $first, $last, $nth

Open Source and Public Domain Initiatives• Informix Node.js driver update (Node.js v4.4.5 LTS)

As a web application developer, I want to use a native node.js driver for Informix database server and be able to download/install it through the Node.js package ecosystem (npm). In addition, I want to be able to use all the supported APIs from latest stable version of node.js (v4.4.5 LTS) within my application.
