vacuum_chunk_size

Maximum read buffer size for background vacuuming operation

During vacuuming, the size of the chunks that are written in the background. The value is in bytes.

Default Value

If the vacuum_chunk_size option is not defined, the default value of 655360 is used.

Example

vacuum_chunk_size=655360

Database Configuration Options

This option key is associated with the RDM_DB handle (or RDM_CPP::Db for C++) and can be set using one of the following functions:

• SQLSetConnectAttr()
• rdm_dbSetOption()
• rdm_dbSetOptions()
• RDM_CPP::Db::SetOption()
• RDM_CPP::Db::SetOptions()

The option key can also be associated with the RDM_TFS handle (or RDM_CPP::TFS for C++) which will be inherited by the next RDM_DB handle (or RDM_CPP::Db for C++) allocated. Modifications to the RDM_TFS after the RDM_DB is allocated have no effect on the allocated RDM_DB. The following functions can be used to set the key/values to be inherited later:

• rdm_tfsSetOptions()
• rdm_tfsSetOption()
• RDM_CPP::TFS::SetOption()
• RDM_CPP::TFS::SetOptions()
