i find that there are two types of clients, I have a lot of write requests, which is more efficient?

[z7658329]

1. my first question:

use jdbc： https://github.com/ClickHouse/clickhouse-java/blob/main/examples/jdbc/src/main/java/com/clickhouse/examples/jdbc/Basic.java

use client: https://github.com/ClickHouse/clickhouse-java/blob/main/examples/client/src/main/java/com/clickhouse/examples/jdbc/Main.java

I have a lot of write requests, and need to write in batch mode, so which is more efficient? can any one tell me, thanks!

2. my second question: dose client support config retry count ? i want retry 3 times when write to ck error

@z7658329 as far as I may see from their code and documentation:

• just client - is client abstraction of http/file/grpc client. It is not wrapped with JDBC API
• jdbc - is "just client" wrapped with JDBC

Performance will depend on your use case and the destination your are writing to. Would you describe it more?
