HI friends ,
I am new in Google Big query . Currently I am trying to create a table/view based on data of few different tables.
let us assume the query is like this :
create table datasetC.TableA as
select col1, col2, ..... from (
select col1,col2,col3 ,sum(col5),sum(col6) .....
datasetA.tableA left join datasetA. tableb left join datasetA.tablec ) inner join ( select ....... datasetA.tablea ,datasetA.tableb)
union all
select col1, col2, ..... from (
select col1,col2,col3 ,sum(col5),sum(col6) .....
datasetB.tableB left join datasetB.tableC left join datasetB.tableD ) inner join ( select ....... datasetB.tablee ,datasetB.tablef)
Now these tables are being refreshed at different times and while loading data in our table, we may have some tables which are yet to be refreshed.
Is there any way to set auto sync of the table just like we have materialised view.
normal view is not reliable as we have very huge data (around 6 tables with 50+ TB of data ) and we get memory issue.
any advice will be helpful .
Thanks in advance
