If you exhaust memory and eject values to disk, or you change the eviction policy to full eviction, then it can become O(log n). When you insert in bulk, there might be insertions that result in an overflow (and thus splits) and this needs to be carried out recursively to the top of the tree. rev2022.11.15.43034.

The document ID key names will be based off the document files provided. This comes from using a new bulk insertion algorithm. All temporarily stored items of the current node get bulk loaded into a new R-tree (thesource tree) using the OMT algorithm. The implementation often needs to lookup nodes to get their bounding box, without the need of requesting any other things (like their children). The Couchbase .NET Client doesn't currently support bulk inserts. Couchbase is JSON database that excels in high volume transactions.

A couple of things to note, This tool only loads monolithic document files, will try to create an ID automatically if one isnt provided with -d and will require some fine-tuning of the root with -r if no documents load. Changes to the current data structure (which are the first code fragments that were written for GeoCouch) could lead to even fewer lookups.
