NIfi: How to ingest a big table -


i trying ingest big table in nifi using querydatabasetable or executesql. doesn't seem work.. same query works smaller tables.

thoughts?

thanks

what kind of error getting? may running following:

https://issues.apache.org/jira/browse/nifi-1251

if using nifi 1.0 can use generatetablefetch processor. allows choose "page" (aka partition) size, , generate sql statements, each of grab 1 "page" of data. can route executesql , retrieve smaller sets of results @ time. if have nifi cluster, can route generatetablefetch remote process group points @ input port on same cluster, (which distribute sql statements across cluster), input port can connected executesql. allows fetch rows table in parallel.
