elastic-vandelay is an importer-exporter utility to import / export data to / from Elasticsearch v7.
To export data from Elasticsearch to a file (use the appropriate binary for your platform):
./bin/elastic-vandelay_darwin_amd64 export --source-url=http://localhost:9200/ --source-index=index-to-export --dest-file=exported-index
The export will result in two files: dest-file will be the exported data and dest-file-mapping.json will be the mappings.
The time-* fields are optional, they can be specified to limit the data exported based on a time field in the data; the format for the times must be YYYY.MM.DD HH:MM:SS.
If the dest-file name specified ends in .gz, the data file will be gzipped.
To import the data file into Elasticsearch (use the appropriate binary for your platform):
./bin/elastic-vandelay_darwin_amd64 import --source-file=./exported-index --dest-url=http://127.0.0.1:9200 --dest-index=new-index
If the source filename specified ends in .gz, the file will be gunzipped first.
