Supported and unsupported features
Supported and unsupported Cassandra and DSE Search features.
CQL-based Solr cores require a new type mapping version 2. A CQL table must be created in Cassandra before creating the Solr core. The schema corresponding to a CQL table using a compound primary key requires a special syntax.
Unsupported Cassandra features
DSE Search does not support:
- Cassandra static columns
- Cassandra compound primary keys for COMPACT STORAGE tables
- Cassandra counter columns
- Cassandra super columns
- Cassandra Thrift-compatible tables with column comparators other than UTF-8 or ASCII.
Unsupported Solr features
- Solr schema fields that are both dynamic and multivalued for CQL-based Solr cores (only)
- The deprecated replaceFields request parameters on document updates for CQL-based Solr cores. Use the suggested procedure for inserting/updating data.
- Block joins based on the Lucene BlockJoinQuery in Solr indexes and CQL tables
- Schemaless mode
- Schema updates through the REST API
- org.apache.solr.spelling.IndexBasedSpellChecker and org.apache.solr.spelling.FileBasedSpellChecker (org.apache.solr.spelling.DirectSolrSpellChecker is supported for spell checking)
- The commitWithin parameter
- The SolrCloud CloudSolrServer feature of SolrJ for endpoint discovery and round-robin load balancing
Other unsupported features
DSE Search/Solr does not support JBOD mode.
