In response to the size of the block being greater than the maximum allowed size for the ACT mode, the block is partitioned into multiple sub-blocks. Each of the multiple sub-blocks share a same prediction mode, and the ACT mode is enabled at a sub-block level.

Video coding and decoding techniques, including history-based motion vector prediction with default parameters, are described. One example video processing method includes resetting, for a conversion between a video unit of a video and a bitstream of the video, a history-based motion vector prediction (HMVP) table of size N by adding K HMVP motion candidates to the HMVP table, where the K HMVP motion candidates have default values, where N and K are positive integers, and where K≤N; and performing the conversion between the video unit and the bitstream using the HMVP table resulting from the resetting.

An exemplary method for visual media processing includes performing a conversion between a current video block of a visual media data and a bitstream representation of the visual media data in accordance with a conditional signaling rule. The current video block is disabled from using an intra sub-block partitioning (ISP) split mode which divides the current video block into sub-blocks depending on dimensions of the current video block. In case that the conversion is associated with disabling use of the ISP split mode, the conditional signaling rule specifies selectively including in the bitstream representation a first syntax element indicating that a luma component of a sub-block of the current video block includes non-zero coefficient values. The selectively including is based at least on one or more other syntax elements having non-zero coefficient values of one or more previous sub-blocks included in the bitstream representation.

A method includes, in response to receiving an incoming service request and establishing a call chain of pods of a service mesh network, setting a retry locker parameter to a locked state for each pod in the call chain. A locked retry locker parameter prevents the pod from initiating retries of a service request. The method includes, in response to determining that a pod in the call chain is unavailable, setting the retry locker parameter to an unlocked state for a previous pod just prior to the pod that is unavailable. The unlocked state allows a retry to the pod that is unavailable. In response to the previous pod reaching a retry limit, the method includes setting the retry locker parameter to unlocked for each pod in the call chain and sending a service termination message to a service requester.
