Hi Dev,

+1  for the 0.206 upgrade of Presto.
Currently, while running some test (TPCH) queries on 500GB data, we
observed some memory issues in the presto cluster.
Couldn't narrow down the exact memory problem in the presto. We restart
cluster as a workaround.
Hoping that issue is fixed in latest release.

Thanks and regards
Ajantha
