How to import into two clusters

[jesseduffield]

I'm upgrading from cluster version 2.4 to 7.17 and rather than do the upgrade in-place, I'm standing up two clusters and writing to both with the plan of eventually removing the old cluster.

I'm using the repository pattern to do this which is working well for creating individual documents in ES, however I'm not sure how to achieve the same behaviour when it comes to importing ActiveRecord objects in bulk.

Currently I'm going 'MyModel.import(...)' but I want a way of either:

• importing via my two repositories (which have their own index_name and client defined)
• passing the ES client into the import method as an argument (the import method currently takes an index_name argument, but not a client argument).

I'm using version 7.2.1 of the gem.

How could I go about this? Thanks.
