Hello,
Just like Monetdb or Vertica, Clickhouse is a column-store database, claiming to be the fastest in the world. It's available on Cloud (like Snowflake), linux and macos (and here for free, it's open-source). it's also very well ranked in analytics database https://db-engines.com/en/system/ClickHouse and it would be a good differenciator with competitors.
https://clickhouse.com/
it has became more popular than Greenplum that is supported : (black snowflake, red greenplum, orange clickhouse)
Best regards,
Simon
