ElasticTools - high-speed utilities for ElasticSearch data manipulations

ElasticTools is a python package developed as a handy utility for cases when it comes to streaming, manipulation or processing of any sort of data stored (or prone to be stored) within ElasticSearch.

The key features are:

• Highly performant. Written purely in python with a dense usage of concurrency thanks to AsyncIO.

• Intuitive. Though almost every commandline argument has a detailed explanation of what is it and why we need it, one can intuitively answer those questions.

Installation

Create and activate a virtual environment

python3 -m venv venv
source venv/bin/activate

Install the package using pip

pip install elastic-tools

Usage

1. Dump Elasticsearch index

elasticdump --elastic_address <ES_ADDRESS> --index <INDEX_NAME> --output_dir <TARGET_DIRECTORY> --chunk_size <CHUNK_SIZE>

Example call:

elasticdump --elastic_address localhost:9200 --index products --output_dir ./dump/ --chunk_size 500

2. Restore Elasticsearch index

elasticload --elastic_address <ES_ADDRESS> --index <INDEX_NAME> --input_dir <DIR_WITH_DUMPED_DATA> --chunk_size <CHUNK_SIZE> --connection_pool_size <PARALLEL_CONNECTIONS_COUNT> --mode <MODE>

Example call:

elasticload --elastic_address localhost:9200 --index products --input_dir ./dump/ --chunk_size 1000

Based on the situation you may want to load only data or both data and settings. For this purposes mode argument is very helpful. Run mongo2elastic -h for more info.

3. Stream data from MongoDB to Elasticsearch

mongo2elastic --mongo_address <MONGO_ADDRESS> --mongo_db <MONGO_DATABASE_NAME> --mongo_collection <MONGO_COLLECTION_NAME> --elastic_address <ES_ADDRESS> --elastic_index <ES_INDEX_NAME> --batch_size <BATCH_SIZE> --connection_pool_size <CONNECTION_POOL_SIZE> --mode <MODE>

Example call:

mongo2elastic --mongo_address localhost:27017 --mongo_db store --mongo_collection products --elastic_address localhost:9200 --elastic_index products --batch_size 500 --connection_pool_size 5 --mode default

Based on the situation you may want to stream only data, only updates or both. For this purposes mode argument is very helpful. Run mongo2elastic -h for more info.
