log_tick no longer logged by default; log_time can be disabled

The SDK no longer injects the log_tick timeline column into logged data by default. The log_time timeline is still injected by default, but can now be disabled.

The initial defaults are controlled by environment variables, read once on first use:

They can also be toggled at runtime, either on the active recording or on a specific RecordingStream:

import rerun as rr

rr.set_log_tick_enabled(True)  # opt in to `log_tick` on the active recording
rr.set_log_time_enabled(False)  # opt out of `log_time` on the active recording

rec = rr.RecordingStream("rerun_example_my_app")
rec.set_log_tick_enabled(True)  # …or on a specific recording

If you relied on the log_tick timeline being present, set RERUN_LOG_TICK=1 (or call set_log_tick_enabled(true)) to restore the old behavior.

rerun.recording module removed

The rerun.recording module — Recording, RRDArchive, load_recording, load_archive — has been removed, having been deprecated in 0.32. The related rr.send_recording(), RecordingStream.send_recording(), Recording.from_chunks(), and DatasetEntry.download_segment() are removed as well.

Use rerun.experimental.RrdReader instead. See the 0.32 migration guide for more details.

Remove embedded base64-encoded table blueprints & replace with blueprint registration

Table blueprints are no longer read from the Arrow schema metadata key rerun:table_blueprint. If you previously stored base64:… encoded .rbl bytes in table metadata, export that blueprint as a regular .rbl file and register it with TableEntry.register_blueprint(...) instead. Tables without a registered blueprint fall back to Arrow field metadata and viewer heuristics.

DatasetEntry.manifest() deprecated

DatasetEntry.manifest() was always intended for internal and debugging use only and should never have been part of the public API. It is now marked @deprecated and will be removed in a future release. No public replacement is offered.

Remove previously deprecated SDK methods for custom indices

The DatasetEntry methods create_fts_search_index, create_vector_search_index, delete_search_indexes, search_fts, and search_vector have been removed, having been deprecated in 0.31.

This change does not impact your ability to search through your dataset via dataframe queries.

rr.send_dataframe is now stricter and built on Chunk.from_record_batch

rr.send_dataframe / rr.send_record_batch are now thin wrappers over the new rerun.experimental.Chunk.from_record_batch (and Chunk.from_dataframe), which turns an Arrow record batch into one chunk per entity path. This makes the Arrow → chunk interpretation a first-class, well-specified capability, but it changes a few behaviors that previously happened silently.

Consequently, the following breaking behavior changes are introduced:

• A batch with no index column now raises instead of silently logging static data. Opt in for a static chunk explicitly with index=None for static, or specify a column to use as index with index=<column> for temporal chunk.
• Entity-path recognition from a column name now requires a leading /. Names without it are no longer parsed for an entity path: foo and foo:bar previously became the entity /foo, and now land on the root entity / as components. Only /entity:component names are split. (Column names emitted by the Rerun SDK always have the / prefix.)
• As a consequence, property:… columns now land on the root entity / rather than an entity named property. Neither map back to /__properties — proper handling of this is not yet implemented.
• component_type is no longer defaulted to the literal "Unknown" when absent; it is left unset.

ParquetReader column rules removed in favor of lenses

rerun.experimental.ParquetReader no longer accepts the column_rules parameter, and the ColumnRule class has been removed. ParquetReader is now a pure reader — it turns raw parquet columns into grouped, time-indexed chunks of struct/scalar components. Mapping those struct fields into Rerun archetypes is now done with lenses on the reader's .stream().

SaveScreenshot gRPC endpoint moved to new ViewerControlService

Previously, the SaveScreenshot gRPC endpoint was part of the MessageProxyService.
