Functions ¶
func AddHandler ¶
AddHandler adds the given handler to the handler set.
Types ¶
type Database ¶
type Database struct {
// contains filtered or unexported fields
}
Database is a wrapper around Dolt's database object, allowing for functionality specific to Doltgres (such as system tables).
func (Database) GetTableInsensitive ¶
GetTableInsensitive implements the interface sql.DatabaseSchema.
func (Database) GetTableNames ¶
GetTableNames implements the interface sql.DatabaseSchema.
func (Database) SchemaName ¶
type Handler ¶
type Handler interface {
// Name returns the name of the table.
Name() string
// RowIter returns a sql.RowIter that returns the rows of the table.
RowIter(ctx *sql.Context, partition sql.Partition) (sql.RowIter, error)
// PkSchema returns the table's schema.
PkSchema() sql.PrimaryKeySchema
}
Handler is an interface that controls how data is represented for some table.
type IndexedTableHandler ¶ added in v0.52.0
type IndexedTableHandler interface {
Handler
// Indexes returns the table's indexes.
Indexes() ([]sql.Index, error)
// LookupPartitions returns a sql.PartitionIter that can be used to look up rows in the table using the given lookup
LookupPartitions(context *sql.Context, lookup sql.IndexLookup) (sql.PartitionIter, error)
}
type VirtualTable ¶
type VirtualTable struct {
// contains filtered or unexported fields
}
VirtualTable represents a table that does not enforce any particular storage of its data.
