Product Features

Open all Close all

Integrated Metadata

    Specialized External Tables

  • Big Data SQL gives users a single location to catalog and secure data in Hadoop and NoSQL systems: Oracle Database.

    • Seamless Integration

  • Seamless metadata integration and queries which join data from Oracle Database with data from Hadoop and NoSQL databases.

    • Automatic Mappings and Access

  • Utilities and conversion routines support automatic mappings from metadata stored in HCatalog (or the Hive Metastore) to Oracle Tables. Enhanced access parameters give administrators the flexibility to control column mapping and data access behavior.

    • Multi-Cluster Support

  • Multiple cluster support enables one Oracle Database to query multiple Hadoop clusters and/or NoSQL systems within a single query.

Optimized Performance

    Smart Scan

  • Locally filtered data
  • Join optimization via Bloom filters
  • Scoring for data mining models and enhanced processing for JSON or XML

    Optimizations for External Storage Formats

  • Prune partitions from tables managed by Apache Hive
  • Minimize I/O on files stored in Apache Parquet and Apache ORC formats
  • Enable remote reads on data stored in Oracle NoSQL Database or Apache HBase

    Storage Indexes

  • Storage Index technology ensures that data blocks that are not relevant to the query are not read.

Secure across All Data

    Simplification

  • Standard Oracle Database roles and privileges to govern access to data across platforms, simplifying security set up through a unified system.

    • Data Redaction

  • Ensures that sensitive information is obscured when accessed by unauthorized users.

    • Advanced Security Functions

  • Virtual Private Database functionality to better enforce governance policies.

Life Cycle Management

    Copy to Hadoop

    Oracle Big Data SQL includes the Oracle Copy to Hadoop utility enabling data copy in:

  • Parquet or ORC file formats
  • Oracle Data Pump Formats

    • Smart Scan on TableSpaces in HDFS

  • Enables immutable archive data within a table to reside in HDFS. Database queries access this data exploiting the optimized access and storage structures (like indexes) for fast query performance.
