Alexander Lapin commented on IGNITE-11287:
------------------------------------------

Test plan draft.
 # –°heck that requests go to the expected number of nodes for different combinations of conditions
 ## Transactional
 ### No Params
 #### Select
 ##### Different partition tree options(All/NONE/Group/CONST) produced by different query
types.
 #### DML

 ##### - // -
 ### With Params
 #### - // -
 ## Non-Transactional

 ### - // -
 # Check that request/response functionality works fine if server response lacks partition
result.
 # Check that partition result is supplied only in case of rendezvous affinity function without
custom filters.
 # Check that best effort functionality works fine for different partitions count.
 # –°heck that a change in topology leads to jdbc thin affinity cache invalidation.
 ## Topology changed during partition result retrieval.
 ## Topology changed during cache distribution retrieval.
 ## Topology changed during best-effort-affinity-unrelated query.
 # Check that jdbc thin best effort affinity works fine if cache is full and new data still
coming. For given case we probably should decrease cache boundaries.
 # Check that proper connection is used if set of nodes we are connected to and set of nodes
derived from partitions
 ## Fully intersect;
 ## Partially intersect;
 ## 
Doesn't intersect, i.e.
||User Specified||Derived from partitons||
|host:port1 - > UUID1
host:port2 -> UUID2|partition1 -> UUID3|
No intersection, so random connection should be used.
 # Check client reconnection after failure.
 # Check that jdbc thin best effort affinity skipped if it is switched off.
