table region split

Hi,

I don't understand very clearly about the table region split.
If I have 10 million rows,1000MB data size, in a table,
how many region will it split?
Thank you

Re: table region split

Posted by stack <st...@duboce.net>.
As soon as any hfile/storefile in a region
exceeds hbase.hregion.max.filesize -- 256M by default -- the region will
schedule a split.

1000MB should make ~5 regions but it depends also on your schema.  If data
spread across more than one family then region may carry more than 256M
before it splits.

How many regions are you getting?
