pos_cache is used to speed up opening POS in databases with large number of products. In some cases it's still not enough and thousands of records cannot be cached in a single request, because reading information may take more time than maximum allowed. As a workaround, this commit adds posibility to split request into few small requests. To activate the feature set system parameter ``pos_cache.limit_products_per_request`` to appropriate value depending on your server capacity. --- opw-2439347 closes odoo/odoo#66995 X-original-commit: fe7718d02f7539959616b0e6f56d4354c768339b Signed-off-by: pimodoo <pimodoo@users.noreply.github.com>
