What is Apache TsFile?

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.

What is Parseable?

Parseable's 3.0 turns a log store into a logs, metrics, traces and APM console.

Parseable has spent the 2.9 line hardening a multi-tenant ingestion engine — API keys, OAuth sync, tenant quotas, credential masking, and a run of injection and path-traversal fixes contributed from outside the core team. Version 3.0.0 collects that groundwork into a platform release: PromQL-based alerts, dashboard templates, dataset tagging, trace and ingestion endpoints, service maps and APM in the Prism UI, and a custom-provider option in the LLM flow. The ingestion story also changed shape, with fluent-bit dropped from the scripts in favour of an OpenTelemetry collector.

TsFile is quietly rebuilding itself as an Arrow-speaking interchange format

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.

Parseable's 3.0 turns a log store into a logs, metrics, traces and APM console.

◆ Current state

Parseable has spent the 2.9 line hardening a multi-tenant ingestion engine — API keys, OAuth sync, tenant quotas, credential masking, and a run of injection and path-traversal fixes contributed from outside the core team. Version 3.0.0 collects that groundwork into a platform release: PromQL-based alerts, dashboard templates, dataset tagging, trace and ingestion endpoints, service maps and APM in the Prism UI, and a custom-provider option in the LLM flow. The ingestion story also changed shape, with fluent-bit dropped from the scripts in favour of an OpenTelemetry collector.

◆ Where it's heading

The direction is consolidation: rather than being the cheap object-store log backend that something else queries, Parseable is absorbing the query, alerting and dashboard layers that normally sit above it. PromQL support is the clearest tell — it targets teams whose alert rules are already written for a Prometheus-shaped world. Performance work is tracking that ambition too, with zstd manifests, configurable concurrent object-store calls and faster field-stats sitting alongside the feature list.

◆ Prediction

The next releases most likely fill in the metrics side to match the logs side — deeper PromQL coverage and more dashboard and alert templates — while the 3.0 UI migrations settle through point releases. Whether the LLM provider hook grows into anything beyond configuration isn't visible from these entries.
