Note:
Original topic: DeltaTree Index参考的是哪篇论文
I would like to ask which paper the Delta Tree Index introduced in this blog refers to?TiFlash Source Code Reading (6) Design and Implementation Analysis of DeltaTree Index | PingCAP
If there are references to other columnar storage systems, you can also post them, thank you~
The one I currently see as more similar is this one: Positional Update Handling in Column Stores
They are all based on the evolution of LSM Tree. The implementation of LSM Tree can refer to Google LevelDB.

I am not asking about RocksDB. I am specifically referring to the in-memory data structure for incremental updates in TiFlash.

No more information～
The DeltaTree engine of TiFlash implements the standard storage engine interface IStorage for Clickhouse data tables, allowing direct access through Clickhouse SQL. This enables simple read and write operations on the table’s data without introducing TiDB and TiKV, providing great convenience for integration testing and debugging. The standard read and write operations on the Clickhouse storage engine are implemented through BlockInputStream and BlockOutputStream, corresponding to writing and reading, respectively, and DeltaTree is no exception. The basic unit of writing and reading is Block (please refer to Block.h). Block organizes data by columns , and these columns together constitute several rows of data.

All valuable content, here to learn.
Bookmark, bookmark. It’s too dry.
It is Positional Update Handling in Column Stores.
Great, I’ll save this for later.
