In their own words
Apache Hive
Apache Hive is a distributed data warehouse system for reading, writing, and managing large datasets with SQL. Its Metastore keeps shared metadata for tables and partitions and serves clients including Hive, Impala, and Spark; HiveServer2 supports concurrent clients through JDBC and ODBC. Hive provides full ACID transactions for ORC tables and insert-only transactions for other formats. Documented storage options include S3, Azure Data Lake, and Google Cloud Storage, and Hive supports Apache Iceberg tables through a StorageHandler. Named integrations include Spark, Presto, and Impala, with Apache Ranger for authorization and Apache Atlas for lineage and governance. Security options described by the project include Kerberos, fine-grained access control, and audit logging; HiveServer2 also lists LDAP, PAM, and custom authentication. The quickstart includes Docker instructions for the server and Metastore. Hive is free open-source software. The installation manual lists Java 8, Maven 3.6.3, Protobuf 2.5, Hadoop 3.3.6, and Tez among current prerequisites; Hive 4.2.x instead requires JDK 21 minimum and works with Hadoop 3.4.1 and Tez 0.10.5.
Comunica
Comunica is an open-source framework for querying knowledge graphs with SPARQL and GraphQL over decentralized RDF on the Web. It can treat multiple sources as one virtual dataset and identify a source type from its URL. Built-in source types include RDF files, SPARQL endpoints, Triple Pattern Fragments, JavaScript RDF sources, serialized datasets, and HDT files. The framework parses Turtle, JSON-LD, RDF/XML, N-Triples, TriG, and N-Quads, and can serialize results as SPARQL JSON, XML, CSV, TSV, or RDF formats. It supports several SPARQL 1.2 specifications, while SPARQL 1.2 entailment regimes and the Graph Store HTTP Protocol are listed as unsupported. The browser client provides SPARQL and GraphQL-LD queries, Solid authentication, selectable sources, and geospatial results. Developers can combine modules into custom engines or add components, and use Comunica in browsers, JavaScript applications, or from the command line. The default SPARQL engine does not query local files; a separate file engine is intended for that purpose. The project is MIT-licensed for open and commercial use.
