Detailed Description

BootstrapCatCache stores hard-coded data needed to bootstrap the entire database catalog.

All other catelog cache will reference this class to load the data needed.

Constructor & Destructor Documentation

BootstrapCatCache()

taco::BootstrapCatCache::BootstrapCatCache

(

)

Initializes the data in the bootstrap systables.

Must Call BootstrapCatCache()::init() to finish initialization. The implementation of this function is in catalog/systables/bootstrap_data.cpp, which is automatically generated from the systable.

~BootstrapCatCache()

taco::BootstrapCatCache::~BootstrapCatCache

(

)

Member Function Documentation

CreateTableDesc()

void taco::BootstrapCatCache::CreateTableDesc ( const std::vector< const SysTable_Column * > &  columns )

private

Creates a TableDesc object for a systable table that consists of the `‘columns’', and insert it into this catalog.

Init()

void taco::BootstrapCatCache::Init

(

)

Finishes the initialization of the bootstrap catalog cache.

Never call this more than once.
