Hi
I got the same message when I tried to lookup fields.
my lookup.csv looks like:
field1,field2,flag
abcdefg1,aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaabbbbbbbbbbbbbbbbbbbbbbcccccccccccccccccccccccccccccccs1,1
abcdefg2,aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaabbbbbbbbbbbbbbbbbbbbbbcccccccccccccccccccccccccccccccs2,1
.. 100,000+ lines ..
When I looked up a field1, it worked fine.
However, I looked up a field2 in the same lookup table, I got the empty csv message.
Is this because of the data lookup gets is very large wit lookup operation with field2..?
so I configured with the following in limits.conf to set to 100MB, and the message went away.
max_memtable_bytes
* Maximum size of static lookup file to use an in-memory index for.
* Defaults to 10000000 in bytes (10MB
I am not sure if this is right way or expected behavior by design...
I hope this helps a bit...
