HTableInterface.batch actions number limit

[Lucian Iordache <lu...@gmail.com>]

Hello,

I have to make a lot of deletes from a hbase table, so I use the batch
method, providing a list of Delete objects.
Is there any limit for the number of Deletes to send in a batch?

Lucian

There's no "recommended size", I guess as long as it fits in memory
it's ok given that not all JVMs are given the same amount of heap.

To be more specific, I was thinking of a recommended number of deletes per
batch.
For example I need to delete 200.000 rows, should I delete them in several
batches or all at once?
(I've noticed that some problems appear for lists containing more than
100.000 deletes)
