… to reduce IO ## Proposed changes Normally we write the separate index files to disk before we merge the index files into an idx compound file. In high-frequency load scenarios, disk IO can become a bottleneck. In order to reduce the pressure on the disk, we write the standalone index file to the RAM directory for the first time, and then write it to the disk when merging it into a composite file. And config `index_inverted_index_by_ram_dir_enable`, default is `false`. <!--Describe your changes.--> ## Further comments If this is a relatively large or complex change, kick off the discussion at [d...@doris.apache.org](mailto:d...@doris.apache.org) by explaining why you chose the solution you did and what alternatives you considered, etc... -- This is an automated message from the Apache Git Service.
