About tsfile

The TsFile extension exposes the read_tsfile(path, table_name) table function for querying Apache TsFile table-model files. It maps TsFile columns to DuckDB types, pushes projections and time predicates into the reader, and streams results in DuckDB vector-sized batches.

The initial release supports one local file and one table per scan. Tree-model files, multi-file scans, automatic table discovery, parallel scans, and TAG/FIELD predicate pushdown are not yet implemented.
