+                        One of distinguishing characteristics of Ignite SQL is the support
for
+                        <a href="https://apacheignite.readme.io/docs/sql-queries#distributed-joins"
target="_blank">distributed SQL JOINs</a>,
+                        which work in both, collocated and non-collocated fashion. When collocated,
the JOINs are
+                        executed on the local data available on each node without having
to move large data sets
+                        across the network. Such collocated approach provides the best scalability
and performance
