Nifi 模板
collect-stream-logs
This flow shows workflow for log collection, aggregation, store and display.
- Ingest logs from folders.
- Listen for syslogs on UDP port.
- Merge syslogs and drop-in logs and persist merged logs to Solr for historical search.
- Dashboard: stream real-time log events to dashboard and enable cross-filter search on historical logs data.
csv-to-json
This flow shows how to convert a CSV entry to a JSON document using ExtractText and ReplaceText.
decompression
This flow demonstrates taking an archive that is created with several levels of compression and then continuously decompressing it using a loop until the archived file is extracted out.
http-get-route
his flow pulls from a web service (example is nifi itself), extracts text from a specific section, makes a routing decision on that extracted value, prepares to write to disk using PutFile.
invoke-http-route
This flow demonstrates how to call an HTTP service based on an incoming FlowFile, and route the original FlowFile based on the status code returned from the invocation. In this example, every 30 seconds a FlowFile is produced, an attribute is added to the FlowFile that sets q=nifi, the google.com is invoked for that FlowFile, and any response with a 200 is routed to a relationship called 200.
retry-count-loop
This process group can be used to maintain a count of how many times a flowfile goes through it. If it reaches some configured threshold it will route to a 'Limit Exceeded' relationship otherwise it will route to 'retry'. Great for processes which you only want to run X number of times before you give up.
split-route
This flow demonstrates splitting a file on line boundaries, routing the splits based on a regex in the content, merging the less important files together for storage somewhere, and sending the higher priority files down another path to take immediate action.
twitter-garden-hose
This flow pulls from Twitter using the garden hose setting; it pulls out some basic attributes from the Json and then routes only those items that are actually tweets.
twitter-solr
This flow shows how to index tweets with Solr using NiFi. Pre-requisites for this flow are NiFi 0.3.0 or later, the creation of a Twitter application, and a running instance of Solr 5.1 or later with a tweets collection. Here are sample steps to set this up (along with Banana dashboard) on HDP Sandbox.
