- This processor pulls data from Solr collections. For its usage, Solr collections - have to fulfil two requirements: -
-- Backwards compatibility to configurations of the GetSolr processor used within releases - of NiFi prior to 1.5 can be realized as follows: -
-- Annotation: The value of property 'Solr Query' actually is not added to parameter 'q' - but to parameter 'fq' for two reasons: -
-- This processor streams the contents of a FlowFile to an Apache Solr - update handler. Any properties added to this processor by the user are - passed to Solr on the update request. If a parameter must be sent multiple - times with different values, properties can follow a naming convention: - name.number, where name is the parameter name and number is a unique number. - Repeating parameters will be sorted by their property name. -
-- Example: To specify multiple 'f' parameters for indexing custom json, the following - properties can be defined: -
-- This will result in sending the following url to Solr: - split=/exams&f=first:/first&f=last:/last&f=grade:/grade -

- For a record created from the following json:
-
- {

- "last": "R",
- "grade": 8,
- "exams": {
- "subject": "Maths",
- "test" : "term1",

- Similarly in case of an array of nested records, this processor would flatten all the nested records into a single solr document, the field name of the field in a child document would follow the format of {Parent Field Name}_{Child Field Name} and would be a multivalued field in the solr document.

- },
- {
- "subject": "Physics",
- "test" : "term1",
- "marks" : 95

- - This processor queries Solr and writes results to FlowFiles. The processor can be used at the - beginning of dataflows and later. Solr results can be written to FlowFiles as Solr XML or using - records functions (supporting CSV, JSON, etc.). Additionally, facets and stats can be retrieved. - They are written to FlowFiles in JSON and sent to designated relationships. -
-- The processor can either be configured to retrieve only top results or full result sets. However, - it should be emphasized that this processor is not designed to export large result sets from Solr. - If the processor is configured to return full result sets, the configured number of rows per - request will be used as batch size and the processor will iteratively increase the start parameter - returning results in one FlowFile per request. The processor will stop iterating through results as - soon as the start parameter exceeds 10000. For exporting large result sets, it can be considered - to make use of the processor GetSolr. Principally, it is also possible to embed this processor into a - dataflow iterating through results making use of the attribute solr.cursor.mark that is added to FlowFiles - for each request. Notice that the usage of Solr's cursor mark requires queries to fulfil several preconditions - (see Solr documentation for deep paging for additional details). -
- -- The most common Solr parameters can be defined via processor properties. Other parameters have to be set via - dynamic properties. -
- -- Parameters that can be set multiple times also have to be defined as dynamic properties - (e. g. fq, facet.field, stats.field). If these parameters must be set multiple times with different values, - properties can follow a naming convention: - name.number, where name is the parameter name and number is a unique number. - Repeating parameters will be sorted by their property name. -
- -- Example: Defining the fq parameter multiple times -
- -| Property Name | -Property Value | -
|---|---|
| fq.1 | -field1:value1 |
-
| fq.2 | -field2:value2 |
-
| fq.3 | -field3:value3 |
-
- This definition will be appended to the Solr URL as follows: - fq=field1:value1&fq=field2:value2&fq=field3:value3 -
- -- Facets and stats can be activated setting the respective Solr parameters as dynamic properties. Example: -
- -| Property Name | -Property Value | -
|---|---|
| facet | -true |
-
| facet.field | -fieldname |
-
| stats | -true |
-
| stats.field | -fieldname |
-
- Multiple fields for facets or stats can be defined in the same way as it is described for multiple filter queries: -
- -| Property Name | -Property Value | -
|---|---|
| facet | -true |
-
| facet.field.1 | -firstField |
-
| facet.field.2 | -secondField |
-
- This definition will be appended to the Solr URL as follows: - facet=true&facet.field=firstField&facet.field=secondField -
