Teiid 10.0.5 Released

Teiid 10.0.5 has been released. It resolves 8 issues:
  • [TEIID-5293] - Add implicit partitioning of joins to non-multisource partitioning as well
  • [TEIID-5288] - OData4 skiptoken is not pulling from the cached results
  • [TEIID-5290] - NOW() function returns the same value for each call in BEGIN...END block
  • [TEIID-5294] - Bug with the name correction logic (TEIID30151 eror)
  • [TEIID-5296] - With MongoDB, timestamp operations throw exceptions when called on null or missing values
  • [TEIID-5297] - With MongoDB, null is returned from timestamp functions if the same function is part of WHERE clause
  • [TEIID-5300] - ClassCastException during query Optimization
  • [TEIID-5301] - With MongoDB, a query with subquery in HAVING clause doesn't return any results
This is the final community release on the 10.0.x line. Please upgrade to 10.1 or 10.2 when possible. 

Planning and work has begun on Teiid 11 and Teiid 10.3 respectively. Teiid 11 will align with WildFly 12, while Teiid 10.3 will likely be the last minor release on 10.x.

Thanks,
Steve

  1. Thanks Steven, which major changes are expected with Teiid 11?

  2. In addition to aligning to WildFly 12 and the corresponding Swarm release, we should make progress on Debezium and general OpenShift integration (some of which has gone into 10.x as well). We should be getting an Exasol translator in 10.3 or 11. I would expect 1 other new source to make it in by then.

Tech Tip: Teiid SQL Language MAKEDEP Hint Explained

In this article I will explain what a MAKEDEP hint is, how and when, why it should be used in Teiid. What: MAKEDEP is query hint.  When a query hint is defined in the SQL query it influences the Teiid query planner to optimize the query in a way that is driven by the user. MAKEDEP means "make this as a dependent join". What is a Dependent Join? For example if we have query like: SELECT * FROM X INNER JOIN Y ON X.PK = Y.FK Where the data for X, and Y are coming from two different sources like Oracle and WebService in Teiid, so in relational algebra you can represent above query as Here the result tuples from node X and node Y are being simultaneously fetched by Teiid query engine, then it joins the both the results inside Teiid engine based on the specified X.PK = Y.PK condition and returns the filtered resulted to the user. simple.. Now, what if, if X table has 5 rows and Y table has 100K rows? In order to do the JOIN naively Teiid need sto read all the 5

Access Teiid from node.js

Are you writing a "node.js" application and would like to access Teiid VDB from it? If "yes", this is currently possible using NPM package "pg" .  Since, Teiid supports the PG transport, you can use this PostgreSQL client for "node.js" for accessing the Teiid. For example if you have VDB called "northwind" deployed on your Teiid server, and it has table called "customers" and you are using default configuration such as user = 'user' password = 'user' host = 127.0.0.1 port = 35432 then you can use following to write simple access program to Teiid var pg = require('pg'); var connectionString = "pg://user:user@localhost:35432/northwind" pg.connect(connectionString, function(err, client) { client.query('SELECT CustomerID, ContactName, ContactTitle FROM Customers', function(err, result) { console.log(result.rows) }); }); If you want
