| 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:
