In some examples, asymmetric quorum protocol based distributed transaction database consistency control may include determining, by a set of primary participants of a cluster, whether a cluster-wide quorum has been reached to commit a transaction associated with a distributed transactional database. Further, based on the determination by the set of primary participants that the cluster-wide quorum has been reached to commit the transaction, instructions to a set of secondary participants of the cluster may be sent to commit the transaction. The set of secondary participants may be configured to comply with a determination by the set of primary participants to commit or to not-commit the transaction.

Asymmetric quorum protocol based distributed transaction database consistency control

A technique includes storing, by a computer, a composite metadata object in a catalog. The composite metadata object represents information about a plurality of database objects of a table structure; the table structure includes a plurality of rows and a plurality of columns; the plurality of database objects is associated with a subset of rows of the plurality of rows; and the plurality of database objects is associated with a plurality of files corresponding to the columns. The technique includes processing, by the computer, a database transaction based on the based on composite metadata object.
