  • Implement Local file system.
  • Add health check command for bydbctl.
  • Implement Inverted Index for SeriesDatabase.
  • Remove Block Level from TSDB.
  • Remove primary index.
  • Measure column-based storage:
    • Data ingestion and retrieval.
    • Flush memory data to disk.
    • Merge memory data and disk data.
  • Stream column-based storage:
    • Data ingestion and retrieval.
    • Flush memory data to disk.
    • Merge memory data and disk data.

Bugs

  • Fix the bug that property merge new tags failed.

Chores

  • Bump go to 1.21.
  • Bump node to 20.9.
  • Bump several tools.
  • Bump all dependencies of Go and Node.
  • Combine banyand and bydbctl Dockerfile.

0.5.0

Features

  • List all properties in a group.
  • Implement Write-ahead Logging
  • Document the clustering.
  • Support multiple roles for banyand server.
  • Support for recovery buffer using wal.
  • Register the node role to the metadata registry.
  • Implement the remote queue to spreading data to data nodes.
  • Implement the distributed query engine.
  • Add mod revision check to write requests.
  • Add TTL to the property.
  • Implement node selector (e.g. PickFirst Selector, Maglev Selector).
  • Unified the buffers separated in blocks to a single buffer in the shard.

Bugs

  • BanyanDB ui unable to load icon.
  • BanyanDB ui type error
  • Fix timer not released

  • Fix data duplicate writing
  • Syncing metadata change events from etcd instead of a local channel.
  • Fix parse environment variables error

Chores

  • Bump several dependencies and tools.
  • Drop redundant "discovery" module from banyand. "metadata" module is enough to play the node and shard discovery role.

0.4.0

  • [UI] Add YAML editor for inputting query criteria.
  • Refactor TopN to support NULL group while keeping seriesID from the source measure.
  • Add a sharded buffer to TSDB to replace Badger's memtable. Badger KV only provides SST.
  • Add a meter system to control the internal metrics.
  • Add multiple metrics for measuring the storage subsystem.
  • Refactor callback of TopNAggregation schema event to avoid deadlock and reload issue.
  • Fix max ModRevision computation with inclusion of TopNAggregation
  • Enhance meter performance
  • Reduce logger creation frequency
  • Add units to memory flags
  • Introduce TSTable to customize the block's structure
  • Add /system endpoint to the monitoring server that displays a list of nodes' system information.

  • Add the Istio scenario stress test based on the data generated by the integration access log.
  • Generalize the index's docID to uint64.
  • Remove redundant ID tag type.
  • Improve granularity of index in measure by leveling up from data point to series.
  • [UI] Add measure CRUD operations.
  • [UI] Add indexRule CRUD operations.
  • [UI] Add indexRuleBinding CRUD operations.

Bugs

  • Fix iterator leaks and ensure proper closure and introduce a closer to guarantee all iterators are closed
  • Fix resource corrupts caused by update indexRule operation
  • Set the maximum integer as the limit for aggregation or grouping operations when performing aggregation or grouping operations in a query plan.
