Senior Analytics Engineer at a tech vendor with 501-1,000 employees
Caching analytics queries has reduced repeated compute and supports faster embedded reporting
The use of DuckDB as a cache for analytics in an embedded analytics product is a valuable feature. It helps manage compute resources efficiently by preventing repeated computations of the same query. This has made it quite handy and quick to implement, which aligns with the fast-paced needs of our engineering team.
Nasir Niamat - PeerSpot reviewer
DB Consultant at i2c
Has offered a cost-effective option despite frequent technical issues and limited market demand
We find some bugs in IBM Informix. Maybe we are using it more aggressively than others. Every month or every second month, we find some bugs in it, which is not ideal. It should be rare, not this frequent. The good thing is they cover those bugs in the next release within weeks or days on demand. IBM Informix should become hybrid and should include AI features similar to other DBMS systems such as Snowflake, Redshift, and DataBricks. This would help its value rise with the market.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"DuckDB is very fast."
"The use of DuckDB as a cache for analytics in an embedded analytics product is a valuable feature."
"The solution is quite stable and reliable; we use it mainly due to its general stable nature."
"It supports multiple applications and business intelligence tools."
"The solution's stability, performance, enhanced functionality, and replication are all great features."
"Flexible Grid provides the ability to automatically create database objects, such as tables, indexes, and stored procedures on all nodes within the grid as a single operation."
"The stability is incredible. I have customers with uptimes of several years."
"Informix can support huge quantities of data with less memory and less capacity."
"It supports in-house-built applications in .NET and VB6"
"My advice is to take it; you will never regret it."
 

Cons

"Sometimes we have memory issues that cause job failures, which we don't fully understand why, but we can rerun the jobs without problems."
"The solution doesn't include functionality like data anonymization."
"Informix is very sturdy, but the problem for us is the marketing action around Informix."
"The technical support services need substantial improvement."
"The solution should offer replication. It would be helpful if the solution would allow us to access third-party tools."
"For me, it's always too expensive. The problem is that Informix sometimes competes with free products, so yes, it's very expensive, but when we're talking about licensed products like SQL Server or anything, the midsize pricing could be significantly improved."
"The solution really doesn't add new features very often. Other solutions are much more actively pushing out upgrades and improvements."
"I really would love to have a QT plugin."
"It would be helpful to have IBM salespeople know that Informix exists, and sell it. Currently, it is completely ignored by IBM."
 

Pricing and Cost Advice

Information not available
"I am not aware of the licensing costs or terms."
"The product has reasonable pricing. We purchase its yearly license."
"For me, it's always too expensive."
"The free edition can be enough to handle moderate-size implementations, but you may want a pay for edition to benefit from more functionality, such as replication."
