A little tool to export/import data from and to the great Elasticsearch.

Even tho Elasticsearch offers its great snapshot functionality, we often encountered the need in development or testing to just quickly clone an ES instance, provide someone with a small dump to import or bootstrap an ES instance. This is why we created this small tool which maybe can serve someone else.

If you have any feedback or contributions please feel free to provide them =).

Right now there is no testsuite, but we've tried the script with various ES versions (1.7.3, 2.3.3 and 5.2.2), data ranging from 1MB to ~9GiB and up to 17 million documents per index.

Tensō requires at least Python 3.5

python3.5 tenso-1.0.1.pyz [-h] [--source_auth_user SOURCE_AUTH_USER]
                     [--source_auth_pass SOURCE_AUTH_PASS] [-cs CHUNK_SIZE]
                     [-st SCROLL_TIME] [--dest_auth_user DEST_AUTH_USER]
                     [--dest_auth_pass DEST_AUTH_PASS]
                     [--max_file_size MAX_FILE_SIZE] [-v]
                     source [destination]

For a simple dump to a file just use:

python3.5 tenso-1.0.1.pyz http://1.2.3.4:9200

This will create a file with the pattern dump-%Y-%m-%d_%H-%M-%S.zip

If you'd like to specify the target file you can add the destination argument

python3.5 tenso-1.0.1.pyz http://1.2.3.4:9200 mydump.zip

Starting from our export example above we would like to import the data in mydump.zip to our local development machine

python3.5 tenso-1.0.1.pyz mydump.zip http://localhost:9200

The same as above could also be achieved in one step using a direct clone

python3.5 tenso-1.0.1.pyz http://1.2.3.4:9200 http://localhost:9200
