offset

问题 Right now I'm working on migrating a site from using an oracle database to use salesforce. For querying the data we are using the latest version of the salesforce rest API. Right now I'm facing a problem paginating results with an offset greater than 2000. I have seen quite a few questions on this topic but none of them seem to fit my problem. So Here are the restrictions I need to fetch the results on chunks of 20 records (that is the page size). I can't just get a bunch of results and then

问题 i just have a simple question, but unfotunately Iwas not able to figure this one out on my own. I want to position a Floating Button at the top left corner of a parent relative layout. The center of the Floating Button shall be centered at the top edge of my parent layout. Thx in advance. XML: <LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:orientation="horizontal" android:padding="75dp"> <LinearLayout android

问题 I am doing data replication in kafka. But, the size of kafka log file is increases very quickly. The size reaches 5 gb in a day. As a solution of this problem, ı want to delete processed data immediately. I am using delete record method in AdminClient to delete offset. But when I look at the log file, data corresponding to that offset is not deleted. RecordsToDelete recordsToDelete = RedcordsToDelete.beforeOffset(offset); TopicPartition topicPartition = new TopicPartition(topicName,partition)

问题 Example sheet: https://docs.google.com/spreadsheets/d/14ma-y3esh1S_EkzHpFBvLb0GzDZZiDsSVXFktH3Rr_E/edit?usp=sharing In column B of ItemData sheet, I have achieved the result I want by copying the formula into every cell in the column, but I want to solve this using ArrayFormula instead. In column C I have achieved the same result using ArrayFormula. However, for addition, column C is referring to cells in column B, while column B is referring to cells in column B. I.e. every cell in column B

问题 I need to make an offset parallel enclosure of an airfoil profile curve, but I cant figure out how to make all the points be equidistant to the points on the primary profile curve at desired distance. this is my example airfoil profile this is my best and not good approach EDIT @Patrick Solution for distance 0.2 回答1: You'll have to special-case slopes of infinity/zero, but the basic approach is to use interpolation to calculate the slope at a point, and then find the perpendicular slope, and

问题 In Node.js, is there any way of getting the current offset of a file descriptor or stream? Presently, it is possible to set the offset of a file descriptor, but there seems to be no way to get it. In C, getting the offset of a file stream is done via ftell, and a file descriptor via lseek(fd, 0, SEEK_CUR). Example If a Node.js program needs to check whether there is prior data in a file after opening it in append mode, a call to ftell would help in this case. This can be done in C as follows:

问题 I have a Straight Skeleton algorithm implemented in Python and would like to use it to offset the edges of a polygon. I have seen several papers suggesting this offsetting approach unfortunately none of them provides specific information on how to achieve it. Among them: A CGAL implementation of the Straight Skeleton of a Simple 2D Polygon with Holes Since the very definition of a Straight Skeleton is based on the continuous wavefront or grassfire propagation of the edges, it is specially

问题 How will kafka deal with a call to KafkaConsumer.commitAsync(Map<TopicPartition, OffsetAndMetadata> offsets, OffsetCommitCallback callback) when offset value for a topic is given as a lesser value than a previous invocation? 回答1: It will simply set the offset of the partition to the value you specified,so next time you will consume you message from commitedOffset+1. The javadoc of commitAsync() says: The committed offset should be the next message your application will consume,i.e.
