Presto is an open source SQL query engine designed to run queries on data stored in Hadoop or in traditional databases.
Teradata supported development of Presto followed the acquisition of Hadapt and Revelytix.
If you have a cluster of nodes with MariaDB MaxScale and you want all the nodes of the cluster to have a similar load and not to be be penalized for queries or writes to the database, you can mount the MaxScale product in front of the MariaDB cluster. MaxScale will balance the requests based on what is being sent to each node to have an equitable load and will cache the queries that it sends to each one. This optimizes the response time to database queries and spreads the load out among all nodes in a similar way.

Presto is for interactive simple queries, where Hive is for reliable processing. If you have a fact-dim join, presto is great..however for fact-fact joins presto is not the solution.. Presto is a great replacement for proprietary technology like Vertica

Linking, embedding links and adding images is easy enough.
Once you have become familiar with the interface, Presto becomes very quick & easy to use (but, you have to practice & repeat to know what you are doing - it is not as intuitive as one would hope).
Organizing & design is fairly simple with click & drag parameters.

Presto was not designed for large fact fact joins. This is by design as presto does not leverage disk and used memory for processing which in turn makes it fast.. However, this is a tradeoff..in an ideal world, people would like to use one system for all their use cases, and presto should get exhaustive by solving this problem.
Resource allocation is not similar to YARN and presto has a priority queue based query resource allocation..so a query that takes long takes longer...this might be alleviated by giving some more control back to the user to define priority/override.
UDF Support is not available in presto. You will have to write your own functions..while this is good for performance, it comes at a huge overhead of building exclusively for presto and not being interoperable with other systems like Hive, SparkSQL etc.

MariaDB MaxScale is a powerful tool and easy to use. It has helped us a lot to improve the performance of our database queries. It implements a security layer that acts as a firewall for the databases, masks the data, or limits the results of the queries. It also integrates easily with Kafka.

We have launched several inquiries to MariaDB MaxScale support, and they have always responded very quickly. They also want to hold frequent meetings with the client to get their opinion understand how they can help. I see a very human support that is concerned about the customer.

ProxySLQ allows many simultaneous connections and allows the cache of queries in memory but it does not have high availability or scalability natively, only through external tools. HAProxy is not able to perform load balancing in an optimal way.
Instead, MariaDB MaxScale allows high availability, scalability, and data replication to external systems such as Kafka. In addition, MaxScale has a monitor that allows you to see the status of the set of databases.

Presto is good for a templated design appeal. You cannot be too creative via this interface - but, the layout and options make the finalized visual product appealing to customers. The other design products I use are for different purposes and not really comparable to Presto.
