Ming LI created HAWQ-994: ---------------------------- Summary: PL/R UDF need to be separated from postgres process for robustness Key: HAWQ-994 URL: https://issues.apache.org/jira/browse/HAWQ-994 Project: Apache HAWQ Issue Type: New Feature Reporter: Ming LI Assignee: Lei Chang
Background: In previous single node DB, user always deploy testing code on another testing DB. Now the data maintained in HAWQ grows enormously, so it is hard to deploy a testing hawq with the same test data. So user need to run some testing UDF or deploy some UDFs which lack of testing the whole data directly onto hawq in production env, which may crash in PL/R or R code. Sometimes poorly written query leads to postmaster reset causing all running jobs to be cancelled and rolled back. Customer often sees this as a HAWQ issue even if it is a user code issue. So we need to separated from postgres process, and change inter process communication from shared memory to others(e.g. pipe, socket and so on). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
