Map(K, V) with duplicate keys silently loses entries (RowBinary readMap collapses pairs into a JS Map)

#996

Uncompressed streaming inserts emit one HTTP chunk per row, inflating the request body ~50%

#988

· claude opened

In-band mid-stream exceptions are not detected for exec() streams (Arrow/Native) or ResultSet.text(): callers get a raw ECONNRESET "aborted" instead of the server error

#976

Mid-stream exception detection false-positives on any `\r\n` in the body (breaks streaming Parquet + CRLF CSV/TSV) and can hang the event loop

#974

query(): trailing semicolon followed by a comment breaks FORMAT append (SYNTAX_ERROR 62)

#973

[backfill: ClickHouse/clickhouse-js] client.query() unconditionally appends FORMAT after user SETTINGS clause, producing invalid SQL on older ClickHouse servers

#970

Scalar {p:Date} / {p:Date32} query params serialize JS Date as a Unix timestamp, rejected by server

#955

[backfill: ClickHouse/clickhouse-js] insert columns parameter does not backtick-quote identifiers with spaces/special chars

#945

RowBinary: dynamic (runtime-schema) writer — do you need one?

#919

readVariant should return the active type discriminant, not just the value

#910

parseColumnType throws on named Tuple types (Tuple(name Type, ...))
