TraceStoreLayer

from v9.4status Work-in-Progress

TraceStoreLayer renders store-backed trace windows. It registers each source window with its TraceChunkStore, redraws when matching chunks arrive, asks each source-owned materializer for immutable TraceGraphData, wraps that data in TraceGraph, and delegates resolved graphs to TraceGraphLayer.

import {TraceStoreLayer, type TraceStoreLayerSource} from '@deck.gl-community/trace-layers/layers';

Source contract​

Each traceSources entry provides:

  • traceChunkStore
  • traceWindow
  • loadChunk
  • materializeTraceGraphData
  • optional traceGraphFilterOptions
  • optional spanBudget
  • optional onProgress
  • optional onError
<DeckGL
  views={views}
  layers={[
    new TraceStoreLayer({
      id: 'trace-store',
      traceSources: [{traceChunkStore, traceWindow, loadChunk, materializeTraceGraphData}],
      settings
    })
  ]}
/>;

The layer owns registration replacement and finalize cleanup for its active source list. It does not own descriptor catalogs, source-specific graph-data materialization, deck views, viewer widgets, tooltips, or selection state. Use TraceGraphLayer when graphs are already materialized. Use DeckTraceGraph for the full React viewer.
