Flume Solr BlobHandler Configuration Options
Flume accepts events by HTTP POST and GET operations using the HTTPSource Flume source.
HTTPSource transforms JSON input into events by default. You can also configure a BlobHandler for HTTPSource to return events containing the request parameters along with the binary large object (BLOB) uploaded with the request. Because the entire BLOB is buffered in RAM, this usage is not generally appropriate for very large objects.
The Flume Solr BlobHandler supports the following configuration options (required options in bold):
Property Name | Default | Description |
---|---|---|
handler | Must be set to the fully qualified class name (FQCN) org.apache.flume.sink. solr.morphline.BlobHandler. | |
handler.maxBlobLength | 100000000 (100 MB) | Specifies the maximum number of bytes to read and buffer per request. |
This example shows a section for an HTTPSource named httpSrc with a BlobHandler for an agent named agent:
agent.sources.httpSrc.type = org.apache.flume.source.http.HTTPSource agent.sources.httpSrc.port = 5140 agent.sources.httpSrc.handler = org.apache.flume.sink.solr.morphline.BlobHandler agent.sources.httpSrc.handler.maxBlobLength = 2000000000 agent.sources.httpSrc.interceptors = uuidinterceptor agent.sources.httpSrc.interceptors.uuidinterceptor.type = org.apache.flume.sink.solr.morphline.UUIDInterceptor$Builder agent.sources.httpSrc.interceptors.uuidinterceptor.headerName = id #agent.sources.httpSrc.interceptors.uuidinterceptor.preserveExisting = false #agent.sources.httpSrc.interceptors.uuidinterceptor.prefix = flume01.example.com agent.sources.httpSrc.channels = memoryChannel
