Create a set of indexes on the tables in an SQLite SEND database to optimize performance of extraction of data from the different functions in the package.
Arguments
- dbToken
Mandatory
Token for the open database connection (seeinitEnvironment
).- replaceExisting
Mandatory, character
Whether an already existing set of indexes in the database may be replaced by a new set of indexes.
Details
All the indexes are named <domain name>_sendigr_<nn>
- .e.g.
TS_sendigr_01
.
If any additional indexes are manually created in the database, avoid to
include 'sendigr' in the name, because all existing indexes with that
included in the name will be initially deleted when execution the function
with replaceExisting = TRUE
.
It's recommended to wait with the creation of the indexes until the major
amount of studies to be loaded in to the database are loaded.
The database must be an SQLite database - no other types of databases are supported by this function.
