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.
