/**
* @file bug519.cpp - Jira task is MAX-345
* - fill t1 with data
* - execute SELECT * INTO OUTFILE '/tmp/t1.csv' FROM t1; against all maxscales->routers[0]
* - DROP TABLE t1
* - LOAD DATA LOCAL INFILE 't1.csv' INTO TABLE t1; using RWSplit
* - check if t1 contains right data
* - DROP t1 again and repeat LOAD DATA LOCAL INFILE 't1.csv' INTO TABLE t1; using ReadConn master
*/
/*
*
* It seems that LOAD DATA LOCAL INFILE is not handled by readwritesplit? Maybe it's a bigger problem
* elsewhere in MaxScale?
*
* I can execute the command, it looks like it is getting sent to the master, but ... no data is actually
* loaded. Does/can MaxScale handle LOAD DATA LOCAL INFILE?
* Comment 1 Kolbe Kegel 2014-09-03 02:39:47 UTC
* The LOAD DATA LOCAL INFILE statement is stuck in "Reading from net" until some timeout is hit:
*
| 22 | maxuser | 192.168.30.38:59996 | test | Query | 10 | Reading from net | load data local
|infile '/Users/kolbe/Devel/seattleparking/Street_Parking_Signs.csv' into table parki | 0.000 |
|
| The client never sees the statement end, though, even after the server has long ago killed its
|connection...
|
| When I start a *new* connection to MaxScale and I try to execute the LOAD DATA LOCAL INFILE statement
|again, I have some problems:
