I have 5 buckets in a 1 node cluster.
Trying to create buckets,shadow datasets and connections on analytics side using this file:
file.txt:
use CouchbaseAnalytics;

create bucket multiple_table_db_6042_simple_table_1 with

;
create shadow dataset multiple_table_db_6042_simple_table_1_shadow on multiple_table_db_6042_simple_table_1;
connect bucket multiple_table_db_6042_simple_table_1 ;
create bucket multiple_table_db_6042_simple_table_10 with

;
create shadow dataset multiple_table_db_6042_simple_table_10_shadow on multiple_table_db_6042_simple_table_10;
connect bucket multiple_table_db_6042_simple_table_10 ;
create bucket multiple_table_db_6042_simple_table_2 with

;
create shadow dataset multiple_table_db_6042_simple_table_2_shadow on multiple_table_db_6042_simple_table_2;
connect bucket multiple_table_db_6042_simple_table_2 ;
create bucket multiple_table_db_6042_simple_table_3 with

;
create shadow dataset multiple_table_db_6042_simple_table_3_shadow on multiple_table_db_6042_simple_table_3;
connect bucket multiple_table_db_6042_simple_table_3 ;
create bucket multiple_table_db_6042_simple_table_4 with

;
create shadow dataset multiple_table_db_6042_simple_table_4_shadow on multiple_table_db_6042_simple_table_4;
connect bucket multiple_table_db_6042_simple_table_4 ;
