Re: [geomesa-users] Questions on filter method of dataframe

[Emilio Lahr-Vivaz <elahrvivaz@xxxxxxxx>]

Hello,

Once you load the dataframe from HBase, it will no longer use the z3 index. There are various options to create in-memory indices on an existing data frame - see https://www.geomesa.org/documentation/user/spark/sparksql.html#in-memory-indexing and https://www.geomesa.org/documentation/user/spark/sparksql.html#spatial-partitioning-and-faster-joins

Thanks,

Emilio

Hi, 

Recently I came across a problem on filter method of dataframe, 

I am wondering that if I got a dataframe reading from Hbase via spark session,

and then built cache for the dataframe, after that I used filter method like st_within on the dataframe,

will the z3-index still be used or not? Thank you!

Best regards,

Evan
