1. A method for processing video data, comprising:
determining whether a partitioning scheme is enabled for a current block based on a rule associated with one or more neighboring samples or blocks of the current block; and
performing a conversion between a video comprising the current block and a bitstream based on the determining;
wherein a neighboring block of the one or more neighboring blocks is set to be unavailable if one or more conditions are not satisfied,
wherein the one or more conditions comprises at least one of: the current block being coded before the neighboring block, the current block being in a different coding tree unit (CTU) row from the neighboring block, the current block being in a different virtual pipeline data unit (VPDU) from the neighboring block, the current block being in a different subpicture from the neighboring block, the current block being in a different slice from the neighboring block, the current block being in a different tile from the neighboring block, the current block being in a different brick from the neighboring block;
wherein the rule specifies that in a case that the neighboring block is unavailable, information from the neighboring block is disallowed to be used to determine whether the partitioning scheme is enabled.
