| 15459 | +It may be useful to precise here, which load balancing algorithms are |
| 15460 | +considered deterministic. Deterministic algorithms will always select the same |
| 15461 | +server for a given client data, assuming the set of available servers has not |
| 15462 | +changed. In general, deterministic algorithms involve hasing or lookups on the |
| 15463 | +incoming requests to choose the target server. However, this is not always the |
| 15464 | +case; "static-rr", for example, can be also considered as deterministic because |
| 15465 | +the server choice is based on the server's static weight, making the selection |
| 15466 | +predictable. "sticky" algorithm provides deterministic routing for the |
| 15467 | +returning clients. |
| 15468 | + |
| 15469 | +As for non-deterministic algorithms, these algorithms select a server based on |
| 15470 | +dynamic server state or simple rotation, so two consecutive requests are not |
| 15471 | +guaranteed to land on the same server. option prefer-last-server is designed |
| 15472 | +specifically for these. roundrobin, leastconn are examples of such algorithms. |
