dna_sequence_service

On startup, will initialize ES index. There is one API endpoint to search the index. This service is setup an average dataset. You can scale it, please see Notes for scaling section.

Setup

1. Run make copy-config
2. Set the values in ./app/elastic_search/config/config.ini
   • data_files_dir_name is not required, will initialize the ES database will JSON files from ./app/data/test_set
   • If you do not wish to use the data in ./dna_sequence/data/test_set. Add JSON files to directory of choice and save relative path in ./app/elastic_search/config/config.ini
3. Run locally or Run on Docker

###### Run locally 1) If you wish to use a virtual environment, run `python3 -m venv .[venv name]` and `. .[venv name]/bin/activate` 1) Run `make install-req` 2) Run `make run-es` 3) Run `make start-app`

##### Run on Docker 1) Run `make run`

Notes for scaling

If you want to scale the index please review: https://www.elastic.co/guide/en/elasticsearch/reference/current/index-modules.html#index-refresh-interval-setting To make changes to the index setting, set those values in the ./app/elastic_search/config/config.ini file. If you want to change the length of the ngram difference, max_ngram_diff must be greater than the difference of min_ngram and max_ngram.
