| Subject: | Speeding UNION with merging indexes | ||
| View as plain text | |||
Hello, MySQL implemented index_merge in version 5... Does MySQL supports something like index_merge to speed up UNION queries? If yes, for which version (assumed release time)? Does anyone know of other DBs systems that can speed up UNION queries? This issue is quite critical for our system.. -thanks in advance.
