@startDocuBlock WalLogfileSuppressShapeInformation @brief suppress shape information --wal.suppress-shape-information

Setting this variable to true will lead to no shape information being written into the write-ahead logfiles for documents or edges. While this is a good optimization for a single server to save memory (and disk space), it it will effectively disable using the write-ahead log as a reliable source for replicating changes to other servers. A master server with this option set to true will not be able to fully reproduce the structure of saved documents after a collection has been deleted. In case a replication client requests a document for which the collection is already deleted, the master will return an empty document. Note that this only affects replication and not normal operation on the master.

Do not set this variable to true on a server that you plan to use as a replication master @endDocuBlock
