Load balancing ignite get requests

Ignite 2.5 - fully replicated 8 node cluster

When running load tests with 1 unique key, only one of the servers gets all
the requests.

Is there something to be enabled in configuration for balancing load
between all machines.


Thanks

Anirudha, also see [1] for built-in load balancing which could be useful

[1]  AdaptiveLoadProbe

Hi,

Well, it depends on a lot of things - if you have small amount of the data,
which can easily fit in memory on each node, then, you can use Replicated
cache.

On the other hand, if you have quite big dataset, you may consider using
Partitioned cache and executing affinity runs.

Thanks, Dmitry,

we seem to have maxed out the performance we can get out of a single ignite
node on a DL380 / whats the best option to scale out and make all replicas
also serve data over get requests?

Hi,

get() operation from client always go to the primary node. If you run
compute task on other nodes, where each will do get() request for that key,
it will read local value. REPLICATED has many other optimizations, for
example for SQL queries.

Thanks!
