Description
Hello,
First of all, thank you for creating such an interesting database.
I tried to use it in my application on Windows and it keeps throwing errors related to WAL files, e.g:
- level=error db=logs_db msg="failed to delete old segment" baseIndex=1 id=2 err="sync D:\Temp\frostdb\databases\logs_db\wal: Access is denied."
- err="failed initializing meta DB: sync D:\Temp\frostdb\databases\logs_db\wal: Access is denied."
It works just fine in Windows WSL2 though.
Here is an initialization excerpt
// Create a registry for metrics
registry := prometheus.NewRegistry()
// Configure index levels with parquet disk compaction for better performance
indexConfig := []*index.LevelConfig{
{
Level: index.L0,
MaxSize: 100 * frostdb.MiB,
Type: index.CompactionTypeParquetDisk,
},
{
Level: index.L1,
MaxSize: 200 * frostdb.MiB,
Type: index.CompactionTypeParquetDisk,
},
{
Level: index.L2,
MaxSize: 500 * frostdb.MiB,
},
}
// Create column store with Windows-friendly options
fmt.Println("Creating column store...")
var columnstore, err = frostdb.New(
frostdb.WithLogger(logger),
frostdb.WithWAL(),
frostdb.WithStoragePath(storagePathDir),
frostdb.WithActiveMemorySize(100*frostdb.MiB),
frostdb.WithRegistry(registry),
frostdb.WithIndexConfig(indexConfig),
frostdb.WithSnapshotTriggerSize(100*frostdb.MiB),
)
if err != nil {
log.Fatalf("Failed to create column store: %v", err)
}
// Defer close and handle potential errors
defer func() {
if closeErr := columnstore.Close(); closeErr != nil {
log.Printf("Warning: Error during column store close: %v", closeErr)
}
}()
