Summary

The .alias property allows creating solids with names that would not pass the solid(name=...) validation. There seem to be two code paths for running this validation. These paths should be merged.

Reproduction

from dagster 

I have a generic wrapper method for merging like this:

public static int MergeMany<T>(this ITable<T> table, IEnumerable<T> records)
{
    return table.Merge()
        .Using(records)
        .OnTargetKey()
        .InsertWhenNotMatched()
        .UpdateWhenMatched()
        .Merge();
}

This works perfectly for almost all tables that I'm using! The

Tell us about the problem you're trying to solve

We have a spec cache CachingSchedulerJobClient which contains a method invalidateCache which invalidates the whole cache wholesale. It would be nice to have a method evictFromCache which invalidates a specific cache entry to allow invalidating portions of the cache.

The functions in this file should be factored out to a separate utility lib as they are reused in bitcoin-etl https://github.com/blockchain-etl/ethereum-etl/blob/develop/ethereumetl/misc_utils.py

if they are not class methods then the method would be invoked for every test and a session would be created for each of those tests.

`class PySparkTest(unittest.TestCase):
@classmethod
def suppress_py4j_logging(cls):
logger = logging.getLogger('py4j')
logger.setLevel(logging.WARN)

Right now, these aren't caught until we try to gob-encode. Consider failing faster in type-checking to avoid too much confusion/loss when it works with local execution.
