Pavel Pereslegin updated IGNITE-7935:
-------------------------------------
Description: Updating each key-value pair independently is very inefficient
when data arrives in batches (examples: cache.putAll(...), dataStreamer,
preloading). Our internal data structures (B+ tree, FreeList) can be used more
efficiently. (was: _Work on improving BPlusTree is being done in another
ticket._
The performance of batch operations in Ignite can be improved by implementing
batch updates on page memory level. We should add support for batch inserting
data rows into FreeList and use it in batch operations to load data through
preloader, dataStreamer, and cache.putAll(...).)
> Add batch update operation to PageMemory and Persistence
