hbase - Select with limit and offset loses many rows in phoenix -


we have on 300m records in phoenix table.

create table if not exists secure.transaction ( salt varchar(4) not null, transaction_id varchar not null, ins_date timestamp,

... transaction_date timestamp, ... constraint pk primary key (salt, transaction_id) ) immutable_rows=true,"keyprefixregionsplitpolicy.prefix_length"=4,split_policy='org.apache.hadoop.hbase.regionserver.keyprefixregionsplitpolicy' ...;

when query

select transaction_date, transaction_id secure.transaction      salt = '1234' , transaction_id '12345%'  order transaction_date limit 100 offset 100;

i see huge gap in middle of result set. looks different hbase regions sorted , sliced data separately.

if ommit offset clause sorting looks correct.

the execution plan query 

    | client 2-chunk 371724 rows 314572847 bytes parallel 2-way range scan on secure.transaction ['8077','0000001019011232'] - ['8077','0000001019011233']  |     |     server top 20 rows sorted [transaction_date desc]                                                                                                |     | client merge sort                                                 | | client offset 10

is bug in phoenix 4.8.1 or sql query?
