Preload
The preload KV store is a wrapper KV store which will first load a set of KV pairs from an external source prior to opening the KV store.
Preparing the KV pairs
Assuming you have an existing bleve index named search.bleve:
$ bleve_export search.bleve search.blexport
This creates a new file search.blexport which is a gzipped sequence of KV pairs.
Preloading a KV store with these KV pairs
Create a new in-memory index with the NewUsing() method as follows:
i, err := bleve.NewUsing(
"",
bleve.NewIndexMapping(),
bleve.Config.DefaultIndexType,
preload.Name,
map[string]interface{}{
"kvStoreName_actual": gtreap.Name,
"preloadpath": pathToBleveExport,
})
Why?
Why would you want to use this? Unfortunately, all of the KV stores supported by bleve either use the syscall or the unsafe package. This means they aren't suitable for environments like Google App Engine. By exporting the KV pairs of an existing bleve index into a simple format, we can then package them up, and preload them into a in-memory index.
