Database limitations on number of projects
Limitations on project totals imposed by databases:
Database | Limitation |
|---|---|
Oracle | No hard limits. |
SQL Server | No hard limit as a query can have any number of parameters, as long as it remains within the maximum batch size — which defaults to 65,536 * Network Packet Size (256MB). In practice, however, 2000 is the limit as this is the maximum number of parameters allowed by SQL Server. (See JRA-38790 - Getting issue details... STATUS for more details.) |
MySQL | No hard limit; maximum query size has to be less than max_allowed_packet, which defaults to 1GB, but can be any value in the range 1024-1073741824 Bytes. |
PostgreSQL | No hard limits; SQL query size is limited to the OS maximum file size. |
HSQLDB | No limits specified, but in practice limited by heap memory. |
