issue: https://github.com/milvus-io/milvus/issues/44399 This PR implements STL_SORT for VARCHAR data type for both RAM and MMAP mode. The general idea is that we deduplicate field values and maintains a posting list for each unique value. The serialization format of the index is: ``` [unique_count][string_offsets][string_data][post_list_offsets][post_list_data][magic_code] string_offsets: array of offsets into string_data section string_data: str_len1, str1, str_len2, str2, ... post_list_offsets: array of offsets into post_list_data section post_list_data: post_list_len1, row_id1, row_id2, ..., post_list_len2, row_id1, row_id2, ... ``` --------- Signed-off-by: SpadeA <tangchenjie1210@gmail.com>

Troubleshooting Docker and Docker Compose
- Confirm that Docker Daemon is running:
$ docker info
-
Ensure that Docker is installed. Refer to the official installation instructions for Docker CE/EE.
-
Start the Docker Daemon if it is not already started.
-
To run Docker without
rootprivileges, create a user group labeleddocker, then add a user to the group withsudo usermod -aG docker $USER. Log out and log back into the terminal for the changes to take effect. For more information, see the official Docker documentation for Managing Docker as a Non-Root User.
- Check the version of Docker-Compose
$ docker compose version
docker compose version 1.25.5, build 8a1c60f6
docker-py version: 4.1.0
CPython version: 3.7.5
OpenSSL version: OpenSSL 1.1.1f 31 Mar 2020
- To install Docker-Compose, see Install Docker Compose
Install jq
Install kubectl
Install helm
- Refer to https://helm.sh/docs/intro/install/
