Description

No document was found for clickhouse multi-table writes.I saw that version 2.3.4 updated the ability of JDBC to read multiple tables, but I could not find an instance of a configuration file with few links on the sink side, nor did it update the function of writing multiple tables in the 2.3.4 document.like this

Now there is such a scheduling task, which needs to synchronize many tables regularly. If each form writes a config separately, it will take quite a long time to start seatunnel service. Before 2.3.4, it is possible to write multiple links in a config and synchronize multiple tables at the same time to reduce service startup times, but increase the consumption of link numbers. So I was concerned about JDBC's multi-table read in 2.3.4. However, if the sink terminal does not support it, I guess it will not be used in production.
