Matteo Bertozzi commented on HBASE-8034:
----------------------------------------
{quote}Can you please point me at what headers are written before data?{quote}
HFileBlock.Writer.finishBlock() and finishBlockAndWriteHeaderAndData()
{quote}...that means KVs will have to be used for detecting imbalance for
fixed-count scheme (size and KV balance may be different)/splitting out new
stripe for sequential data/etc. Do you think it's acceptable?{quote}
yeah, splitting and some other sort of tuning can be the first use case
> record on-disk data size for store file and make it available during writing
