Ask HN: Storage DB for backlinks?

Hey everyone,

Looking for suggestion and recommendations, what would be your ideal choice if you are about to build a backlinks database and running later on PageRank algorithm on it. Our use case is to improve the search relevancy depending on the URL rank.

Considered Storage DBs:

1. Clickhouse 2. ElasticSearch (team is experienced with it, but finding a duplicate URLs etc. over a huge dataset is still clumsy in ElasticSearch) So thought of going with the Clickhouse.

Thanks.
