scala - Akka Actor internal state during shard migration in a cluster -

-

we using akka sharding distribute our running actors across several nodes. actors persistent , keep internal state in database.

now need add actorref "metrics actor", running on each node. each actor in shard supposed send telemetric data metrics actor - must choose right metrics actor running locally on same node. reason is, metric actor gathers data peer node.

now, thinking create metric actor in main method (which runs on each node):

val mvmetrics : actorref = system.actorof(metricsactor("mv"), "mvmetrics")

and pass reference clustersharding inicialisation part of actors props object:

    clustersharding(system).start(         typename = shardname,         entityprops = myshardactor.props(mvmetrics),         settings = clustershardingsettings(system),         extractentityid = idextractor,         extractshardid = shardresolver)

my question is, happen if such created actors migrate between nodes, e.g. node -> b? can imagine migrated props object on node b remains same on node a, actorref remains same , therefore newly created actor sending metrics data original node a?

thanks

how taking advantage of actorref.path? imagine each node has actor named in way, , actor dynamically find relevant metrics actor using path.

i debugging intermittent test failure. purposes want dump lot of debug information if test failed. dumping debug stuff quite slow process produces lot of data, not want every test. i using pytest , yield autouse fixture should work great @pytest.yield_fixture(scope="function", autouse=true) def dump_on_failue(request): prepare_debug_dump() yield if test_failed(request): debug_dump() the problem can't figure out how detect whether test has failed or not. there a questions already , note on pytest website : if request.node.rep_setup.failed: print ("setting test failed!", request.node.nodeid) elif request.node.rep_setup.passed: if request.node.rep_call.failed: print ("executing test failed", request.node.nodeid) unfortunately code not work anymore. there no rep_setup , rep_calls symbols in node object. tried dig request , node object, no luck. anybody knows how detect whether test ...
