Offline configurations en
You can use offline configurations to build indexes. You can set the structure of the index table, method of data processing, parameters for index building, and analyzer plug-ins. The directory for offline configurations must be a number. When you build an index, you must specify the upper-level directory of the configuration directory. The index building program automatically uses the latest configurations in the directory to build the index. The following example shows an offline configuration directory. You can also refer to offline_config.
The schemas directory is required. This directory stores the index schemas of one or more tables. The index schema configuration file is a JSON file. The name of the file consists of the name of the index table and suffix "_schema.json". For more information about the format of the index schema configuration file, see Configure the schema .
The data_tables directory is required. This directory stores data processing configurations of one or more tables. The engine can process raw data based on the configurations in this directory when you build indexes. The data processing configuration file is a JSON file. The name of the file consists of the name of the index table and suffix "_table.json". For more information about the format of the data processing configuration file, see Configure the data table.
The clusters directory is required. This directory stores the specific parameters of one or more index tables. The cluster configuration file is a JSON file. The name of the file consists of the name of the index table and suffix "_cluster.json". For more information about the format of the cluster configuration file, see Configure the cluster.
The plugins directory is optional. This directory stores custom plug-ins used when you build indexes.
analyzer.json is an analyzer configuration file that specifies all analyzers available for the engine. For more information about the format, see Configure the analyzer.
