Descripción

Currently, only [groupBitmap](https://clickhouse.com/docs/en/sql-reference/aggregate-functions/reference/groupbitmap) is [supported](https://github.com/ClickHouse/clickhouse-java/blob/d175cd7d0e8f0427a8e2bc1b20c597990cd507b4/clickhouse-data/src/main/java/com/clickhouse/data/format/ClickHouseRowBinaryProcessor.java#L510-L515) as parameter for a table column of type [AggregateFunction](https://clickhouse.com/docs/en/sql-reference/data-types/aggregatefunction/).

It would be good if [all](https://clickhouse.com/docs/en/sql-reference/aggregate-functions/reference/) aggregate functions are supported.

Línea de trabajo

Inspect ClickHouseRowBinaryProcessor.java around lines 510-515 and review the AggregateFunction and aggregate-function reference documentation. Check merged pull request #1345 and the current implementation first; done means supported AggregateFunction column parameters cover the requested aggregate functions without breaking existing handling.
