Deadlock in LIMIT without ORDER BY query

Affected Versions EXASOL 6.0.0

Problem

In rare occasions a LIMIT (without ORDER BY) query can be stuck in a deadlock. The probability this happening is higher:

  • the more nodes the cluster has
  • the less data is in the base table

Workaround

Use ORDER BY LIMIT instead of LIMIT.
