[GitHub] nifi issue #2310: NIFI-4428: Add PutDruidRecord processor and DruidTranquili...
Github user vakshorton commented on the issue: https://github.com/apache/nifi/pull/2310 @MikeThomsen There is an indexing service that works with Kafka. However, for high volume use cases, this requires a lot of Kafka resources just to ingest data into Druid. Presumably, all that data would have already flowed through and been processed by Nifi. Providing the capability to send the data directly into Druid can really reduce the required hardware resources, management overhead, and usage complexity. ---

Github user vakshorton commented on the issue: https://github.com/apache/nifi/pull/2310 @pvillard31 You are likely seeing a lot of dropped events because the timestamps in the events are out of synch with the server clock. If your segment granularity is set to 10 minutes, late window set to 1 minute and the event timestamp is more than 11 minutes out of synch with the server time, that data is considered "late" (since the target index task will have closed). What kind of ingestion rates on what input volume? Are you seeing a lot of queuing? Can you check your middle manager configuration/resource allocation? ---
[GitHub] nifi issue #2181: NIFI-4428: - Implement PutDruid Processor and Controller
Github user vakshorton commented on the issue: https://github.com/apache/nifi/pull/2181 @mattyb149 As Druid is optimized for OLAP it does not work as an OLTP datastore, The REST API of Druid is for querying and obtaining meta data (like segment schema and time interval), it does not support writes. That is mainly because writes in Druid can only happen after a configured quantity of data (Segment Granularity Spec) has been indexed and organized into a storage segment (schema, bitmap index, aggregate metrics, compression). Only an Indexing job can create a segment (either batch or realtime). Realtime indexing jobs can be created in one of two ways. 1.) Pull via a Firehose (Druid Aware Pull API) created to read the stream source, controlled by a Druid Realtime Node (like the Kafka Indexing Service). 2.) Push via Tranquility (Druid Indexing API) from stream source to Druid Overlord and then MiddleManager Nodes that will make the data immediately queryable while indexing it for storage as a segment. Since the goal is to push data from Nifi into Druid, Tranquility seems like the best option. ---
