Here is my case:
writeIndex function takes about 39% in pprof flame graph. I dive into it
and find out that we use POA consensus, therefore mining addresses have
a big bitmap.
```
func writeIndex(blocknum uint64, changes *historyv2.ChangeSet, bucket string, changeDb kv.RwTx) error {
buf := bytes.NewBuffer(nil)
for _, change := range changes.Changes {
k := dbutils.CompositeKeyWithoutIncarnation(change.Key)
index, err := bitmapdb.Get64(changeDb, bucket, k, math.MaxUint32, math.MaxUint32)
if err != nil {
return fmt.Errorf("find chunk failed: %w", err)
}
index.Add(blocknum)
if err = bitmapdb.WalkChunkWithKeys64(k, index, bitmapdb.ChunkLimit, func(chunkKey []byte, chunk *roaring64.Bitmap) error {
buf.Reset()
if _, err = chunk.WriteTo(buf); err != nil {
return err
}
return changeDb.Put(bucket, chunkKey, common.CopyBytes(buf.Bytes()))
}); err != nil {
return err
}
}
return nil
}
```
assume that a mining address has a big bitmap (Cardinality 400000), then
"writeIndex" will split it into 300 small bitmaps according to
”ChunkLimit“ and next time "writeIndex" will union all small bitmaps
into a big bitmap， then use binary search to split it into 300 small
bitmaps. over and over again.
I think blockNum > index.Maximum(), so that we only need get the last
one of 300 small bitmaps .
