Goden Yao updated HAWQ-994: --------------------------- Fix Version/s: backlog > 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 > Fix For: backlog > > > 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)
