Hi, I'm using TimeUUID/Sort by column name mechanism. The column value can contain text data (in future they may contain image data as well) leading to the possibility of a row out-growing the RAM capacity. Given this background my questions are:
a] How many columns are recommended against one row? Based on my app. needs, I can imagine having 10 million would be a good starting point for the max_limit (based on text data). Also note that my app. will use search in ranges of 100 or 200 columns when there are large number of records(columnar data) without a caching solution in the front. b] What partitioner is recommended? so that the load in the cluster nodes is not largely uneven. c] Would you recommend changing the TimeUUID/Columnar sort mechanism (with a change in the data model) to sort using row key mechanism? If so then what partitioner is recommended? with load not being largely uneven. Thanks
