Features

This section covers cross-cutting capabilities that span more than one subsystem. Where a feature lives mostly inside a single subsystem (e.g. the SQL optimizer is part of pkg/sql/), it is documented under systems. Features here glue several subsystems together.

Pages

• Changefeed (CDC) — pkg/ccl/changefeedccl/: streaming row-level changes to external sinks.
• Backup and restore — pkg/backup/: cluster, database, and table backups; restore.
• Multi-region — pkg/sql/catalog/multiregion/, pkg/ccl/multiregionccl/: REGIONAL/GLOBAL tables, region survival.
• Multi-tenant — pkg/multitenant/, pkg/ccl/multitenantccl/: SQL pods over a shared host KV.
• Cross-cluster replication — pkg/crosscluster/, pkg/ccl/streamingccl/: physical and logical replication.
• Vector index — pkg/sql/vecindex/: ANN over VECTOR columns.
• Workload generator — pkg/workload/, pkg/cmd/workload: TPC-C, KV, ycsb, schemachange.
• Admission control — pkg/util/admission/, pkg/kv/kvserver/kvadmission/: cluster-wide flow and CPU control.
• Disaggregated storage — pkg/storage/shared_storage.go, pkg/cloud/: sharing SST levels across nodes via object storage.
• Store-liveness leases — pkg/kv/kvserver/storeliveness/, pkg/raft/raftstoreliveness/: the new lease/leadership fabric.
