Basic Concepts

  • Filter

    Filters provide powerful features to help users improve the table data processing efficiency of HBase. Users can use the filter predefined in HBase and customize a filter.

  • Coprocessor

    Coprocessors enable users to perform region-level operations and provide functions similar to those of triggers in a relational database management system (RDBMS).

  • Client

    Users can access a server from a client through Java APIs or HBase shell to read and write HBase tables. The HBase client in this document refers to the HBase client installation package downloaded from MRS Manager where the HBase service is installed. The HBase client installation package includes the sample code for accessing HBase through Java APIs.
