RT index config file

General Discussions - English

In the documentation it states:

What you can do with a real-time index:

  • Define index in a configuration file

However, I cannot find documentation of where it goes (data_dir I assume) and how to reference this configuration file to be used when searchd starts.

Can someone please point to the docs regarding RT configuration files?
Or is this a documentation error? Can RT index only be created using online methods (CREATE…or JSON api)?

thanks

I cannot find documentation of where it goes

It goes to path - https://manual.manticoresearch.com/Creating_an_index/Local_indexes/Plain_and_real-time_index_settings#path

Here’s an example of an RT index in plain mode:

index table
{
    type = rt
    path = /path/where/the/index/files/will/be/stored/
    rt_field  = title
    rt_attr_uint = age
    rt_attr_string = color
    stored_fields = title
}

searchd
{
    listen = 9315:mysq
    log = searchd.log
    query_log = query.log
    pid_file = 9315.pid
    binlog_path =
}

Thanks, I got confused between real-time mode and real-time index.
In real-time mode (searchd { data_dir = aaa }), is there no way to define the index beforehand, through a configuration file?

That’s correct. In real-time mode you can use only CREATE TABLE to create indexes. Like in most other databases.
