amazon web services - AWS Elasticache - increase memcached item size limit -

-

im using memcached module on aws elasticache in python flask app (with flask-cache)

when try set file less 1mb need repeatedly access cache, have no issues. when file size increases more mb (the file text file/csv/xlsx etc), following error

error: error 37 memcached_set: success

im guessing because of size limit on memcached item capped @ 1mb. how increase item limit 5-6 mb in aws elasticache ?

are there issues in increasing item size limit in memcached ?

this page lists parameters can tinker in memcached http://docs.aws.amazon.com/amazonelasticache/latest/userguide/cacheparametergroups.memcached.html

if not specify parameter group memcached cluster, default parameter group (default.memcached1.4) used. cannot change values of parameters in default parameter group; however, can create custom parameter group , assign cluster @ time.

create new cache parameter group either aws console or using aws cli , set max_item_size size fits needs. reboot cache cluster change kickin.

enter image description here

on local testing machine, if have memcache installed, can increase object size adding line @ /etc/memcached.conf

# increase object size limit -i 128m

then reboot memcache sudo service memcached restart changes settle in
