Server

  • [Backup] Fixed the restore of tombstones from a backup
  • [Cluster] Added endpoint to remove entry from Raft log
  • [Configuration] Added Indexing.MaxNumberOfConcurrentlyRunningIndexes configuration option (default: null - no limit)
  • [Configuration] Increased dafault value for Indexing.Encrypted.TransactionSizeLimitInMb configuration option depending on the amount of available memory:
    • <= 1GB of RAM or running in 32bits - 96MB
    • <= 4GB of RAM - 128MB
    • <= 16GB of RAM - 256MB
    • <= 64GB of RAM - 512MB
    • > 64GB of RAM - 1024MB
  • [Indexing] Fixed the behavior of recreating indexing writer upon every commit
  • [Indexing] Fixed handling for ERROR_COMMITMENT_LIMIT to treat is as OutOfMemory
  • [Indexing] Reduce amount of IO needed to deal with temporary files
  • [Indexing] Added ability to limit number of concurrently running indexes to reduce the memory and IO usage (Indexing.MaxNumberOfConcurrentlyRunningIndexes)
  • [Indexing] Fixed invalid memory allocation in Lucene
  • [Indexing] Added cluster-wide disable index

  • [Voron] Ensured that we report an alert if an error happened during the flush of data and we recreate the backgroud task
  • [Voron] Fixed unreleased allocations in scratch buffers which made that scratch files were never cleaned up
