It is simple TABLE with ~100 fields all are either timestamp, varchar or double
CREATE TABLE MY_TABLE
(
Row_time TIMESTAMP not null,
Row_id VARCHAR NOT NULL,
A VARCHAR ,
B VARCHAR ,
B VARCHAR ,
D VARCHAR ,
…some more field
..
CONSTRAINT PK PRIMARY KEY (Row_time ROW_TIMESTAMP, Row_id)
) SALT_BUCKETS = 9
And some indexes like the ones below
CREATE INDEX A_GLOBAL_IDX ON MY_TABLE ("A");
CREATE INDEX B_GLOBAL_IDX ON MY_TABLE ("B");
CREATE INDEX C_GLOBAL_IDX ON MY_TABLE ("C");
…
The query is simply select * from MY_TABLE where A="<some value >"
Thanks for helping us out

timestamp mapping
Hi Noam,
Can you pass on the DDL statements for the table and index and the query you
are executing, please?
Thanks!

Hi
I have create a table and used the row timestamp mapping functionality. The key
of the table is <timestamp_column>+<row_id> column. I also created global index
on one of the columns of the table (XXX not one of the key columns).
When I am doing explain select * from my_table where xxx='<value>' I see that
index is not used (even though index is defined on XX column )
CLIENT 9-CHUNK PARALLEL 9-WAY ROUND ROBIN FULL SCAN OVER MY_TABLE
ROW TIMESTAMP FILTER [0, 1506847791496)
SERVER FILTER BY XXX = '<some value>'
When I am adding hint I get the following exception (this is from explain …, I
get similar error when running the actual query )
java.lang.NullPointerException
