问题
We are getting an error while loading data from one table to another. We do some monthly/quarterly roll ups on the first table data which is inserted into another table
The source table has clustered column store index. We have billions of rows in the source data table.
the SELECT part of the load script has a WHERE clause which filters data based on month and year.
The error is below
'The database 'tempdb' has reached its size quota. Partition or delete data, drop indexes, or consult the documentation for possible resolutions.'
回答1:
SQLAzure enforces different limits,some are applicable irrespective of tiers,some limits may be higher depending on your service tier.Below is the way Azure handles those limits
Enforcement of limits
Resources other than CPU, Memory, Log I/O, and Data I/O are enforced by denying new requests when limits are reached. When a database reaches the configured maximum size limit, inserts and updates that increase data size fail, while selects and deletes continue to work. Clients receive an error message depending on the limit that has been reached.
so this answers your question on whether we can increase size of TEMPDB
Below are the limits for TEMPDB
This Page Azure SQL Database Resource Limits contains entire Limits in detail, i will try to add all the details when time permits or when i find the Github page ,so that link rot can be avoided
