We recently ran into an issue where we are hanging we attempting to iterate
through the results from IgniteCache.query. The basic code is as follows:
QueryCursor<Cache.Entry<Ts3SecurityCacheKey, Integer>> queryResults =
ts3KeysMetadataCache.query(new ScanQuery<>());
queryResults.forEach(e -> {
// Do stuff
});
Through debugging, it can be seen that we never reach the code in the forEach
statement or afterwards. It seems like somehow the data was corrupted, since if
we delete the work directory and restart the issue is fixed. I tried getting a
thread dump but it isn't super clear to me what the issue is from looking at
that. There are no blocked threads. Any idea what could be causing this? Also,
is there a configuration setting that would cause the code above to eventually
throw an exception instead of hang forever?
