-----------------------------------
Summary: Import Solr schema to NiFi record schema
Key: NIFI-4514
URL: https://issues.apache.org/jira/browse/NIFI-4514
Project: Apache NiFi
Issue Type: Improvement
Components: Extensions
Reporter: Koji Kawamura
As Solr related components start supporting NiFi record data model, it would be
helpful if NiFi Solr processors can create NiFi record schema from Solr
document schema automatically.
Principally this is possible, by using the Schema API but can be difficult to
implement it right. Known requirements and challenges are:
# Solr provides various different field types for different kinds of data. For
instance, an integer could be derived from an Int, TrieInt (version < 7.0) or
Pint (version >= 7.0) field. This requires a comprehensive fieldtype-datatype
mapping.
# Requires parsing of response json, as the response parsing of Schema API is
not really realized in SolrJ
# Dynamic fields could become a problem
