-------------------------------------
Summary: HDFS Content Repository
Key: NIFI-7320
URL: https://issues.apache.org/jira/browse/NIFI-7320
Project: Apache NiFi
Issue Type: New Feature
Components: Extensions
Affects Versions: 1.12.0
Reporter: Andrew Glowacki
Fix For: 1.12.0
This issue is for a new content repository that stores FlowFile content in HDFS
instead of the local disk. While storage capacity for a NiFi cluster can be
expanded by adding more nodes, this doesn't make sense if the only reason is to
increase content repository storage or I/O capacity.
In addition to just storing all content in HDFS, the repository can also:
* Store content in the local disk as normal, and fallback to HDFS when the
local disk is full
* Store content in HDFS but fallback to a local disk if a failure occurs.
* Store content in the local disk as normal, and only store archived content
in HDFS for longer retention.
