Hi everyone, We are proposing a new feature for Hyracks users to communicate using "message frames" to communicate state to downstream operators. This is meant to be an less invasive alternative to using message tuples and using context objects. This is currently being used to support navigational queries in Graphix.
APE: https://cwiki.apache.org/confluence/display/ASTERIXDB/APE+3:+Message+Frames+for+In-Band+Communication Patch: https://asterix-gerrit.ics.uci.edu/c/asterixdb/+/17731 Issue: https://issues.apache.org/jira/browse/ASTERIXDB-3241 Following the procedure from the last APE, we'll keep this open for 72 hours and pass with either 3 votes or a majority of positive votes.
