What's Changed

New Environment Variable: FASTBCP_ADBC_BATCHCELLS

Added the FASTBCP_ADBC_BATCHCELLS environment variable to control the size (in cells, i.e. rows × columns) of the Arrow record batches fetched by the ADBC connectors (adbc_mssql, adbc_pgsql).

• Default: 500000 (500,000 cells)
• Sizing by cell count keeps batch memory usage predictable across tables of different widths.

See the FASTBCP_ADBC_BATCHCELLS documentation for details.
