Hi
I am new HBase user. I have some doubts regards
functionality of HBase. I am working on HBase, things are going fine but
I am not clear how are things happening. Please help me by answering
these questions.
1. I am inserting data in HBase table and all regions get balanced
across various Regionservers. But what will happens when data increases
and there is not enough space in Regionservers to accommodate all
regions. So I will like this that some regions in Regionserver and some
are at HDFS but not on Regionserver or HBase Regioservers stop taking
new data?
2. When I insert data in HBase table, 3 to 4 mapfiles are generated
for one category, but after some time all mapfiles combines as one file.
Is this we call minor compaction actually?
3. For my application where I will use HBase will have updates in a
table frequently. Should is use some other database as a intermediate to
store data temporarily like MySQL and then do bulk update on HBase or
should I directly do updates on HBase. Please tell which technique will
be more optimized in HBase?
Thanks & Regards
