TsFile is quietly rebuilding itself as an Arrow-speaking interchange format
Apache TsFile is the columnar time-series file format underlying IoTDB, maintained as three parallel implementations in Java, C++ and Python. Recent releases have concentrated on the C++ and Python ends: SIMD paths and parallel reads in 2.4.0, an Arrow-compatible result path from C++ through to Python DataFrames in 2.3.0, and conversion scripts from CSV, Parquet and Arrow into TsFile in 2.3.1. The Java side gets steadier, smaller work — serialized-size calculation, schema modification during writes, encryption configuration.
Neo4j's Virtual Graph lets you run Cypher against Snowflake and BigQuery without moving any data.
Neo4j is expanding Aura's geographic reach (AWS London and Montreal this week) while pushing two substantial capability betas: Virtual Graph — a zero-copy bridge that translates Cypher to SQL against BigQuery, Databricks, and Snowflake — and Multiple Databases in a single instance. The August release also shipped native UUID types in Cypher 25 and ABAC for fine-grained access control.

The Java side gets steadier, smaller work — serialized-size calculation, schema modification during writes, encryption configuration.
The centre of gravity has moved from format features to ecosystem reach. Arrow-backed DataFrames and format converters are not about storing time series better; they are about making TsFile readable by the Python analytics stack without a translation layer, which is the gap that keeps a specialized format confined to its own database. The C++ performance work in 2.4.0 serves the same end, since the Python bindings sit on top of it. Version numbering runs on two lines at once, with 1.1.x backports still shipping alongside the 2.x series.
Given the direction of the Arrow work, the Python interface is the most likely target for further capability rather than the Java one. The notes do not indicate when the 1.1 maintenance line ends.

Neo4j is positioning itself as the graph layer on top of existing data warehouses rather than a replacement for them. Virtual Graph and ABAC together signal a push into enterprise data architectures where teams have data in Snowflake or BigQuery and want graph traversal without ETL. The multiple-databases GA (coming in months per the release) reinforces that Aura is targeting organizations running multiple isolated tenants on a single cluster.
Virtual Graph will likely exit preview with paid pricing attached once the query-pushdown behavior stabilizes; the next move is probably native support for LLM embedding pipelines that stay in Aura without exporting data to a warehouse.
