Re: [geomesa-users] Question on Geomasa datastore
Hi  Emilio,

Thank you so much your patience and help! These links help a lot! I think I need to spend more time reading the geomesa docs now. Really appreciate your help!

Best Regards,
Yifan

Hello,

Due to the nature of NoSQL databases, you generally have to replicate your data more than once in order to answer different query patterns. GeoMesa by default will create several indices [1]. However, you can fully control which indices are created [2] if you want to disable some.

There are some other things you can do as well, such as using UUID-encoding for feature IDs [3], or TWKB geometry serialization [4].

Whichever indices you keep, you may also want to look into configuring HBase to use compression [5].

Thanks,

Emilio

Hi,

 

I’m new to Geomesa. I tried to store data in CSV file to HBase as SimpleFeatureType. My origin CSV file size was 342M but in Hbase, the table size was as below.

The structure of SimpleFeatureType was

I am wondering is it normal that the table size become four times larger than the origin file? Is there anything I can do to fix this? Thank you!
