rupture
An explosive companion to the bleve indexing library
Features
rupture includes the following additions to bleve:
- Flushing batches: Batches of operation which automatically flush to the underlying bleve index.
- Sharded indices: An index-like abstraction built on top of several underlying indices. Sharded indices provide lower write latencies for indices with large amounts of data.
- Index metadata: Track index version for easily managing migrations and schema changes.

Functions ¶
func WriteIndexMetadata ¶
func WriteIndexMetadata(path string, meta *IndexMetadata) error
WriteIndexMetadata writes metadata for the index at the specified path.
Types ¶
type FlushingBatch ¶
type FlushingBatch interface {
// Index adds the specified index operation batch, possibly triggering a
// flush.
Index(id string, data interface{}) error
// Remove adds the specified delete operation to the batch, possibly
// triggering a flush.
Delete(id string) error
// Flush flushes the batch's contents.
Flush() error
}
FlushingBatch is a batch of operations that automatically flushes to the underlying index once it reaches a certain size.
func NewFlushingBatch ¶
func NewFlushingBatch(index bleve.Index, maxBatchSize int) FlushingBatch
NewFlushingBatch creates a new flushing batch for the specified index. Once the number of operations in the batch reaches the specified limit, the batch automatically flushes its operations to the index.
func NewShardedFlushingBatch ¶
func NewShardedFlushingBatch(index ShardedIndex, maxBatchSize int) FlushingBatch
NewShardedFlushingBatch creates a flushing batch with the specified batch size for the specified sharded index.
type IndexMetadata ¶
type IndexMetadata struct {
// The version of the data in the index. This can be useful for tracking
// schema changes or data migrations.
Version int `json:"version"`
}
IndexMetadata contains metadata about a bleve index.
func ReadIndexMetadata ¶
func ReadIndexMetadata(path string) (*IndexMetadata, error)
ReadIndexMetadata returns the metadata for the index at the specified path. If no such index metadata exists, an empty metadata and a nil error are returned.
type ShardedIndex ¶
ShardedIndex an index that is built onto of multiple underlying bleve indices (i.e. shards). Similar to bleve's index aliases, some methods may not be supported.
func NewShardedIndex ¶
func NewShardedIndex(path string, mapping mapping.IndexMapping, numShards int) (ShardedIndex, error)
NewShardedIndex creates a sharded index at the specified path, with the specified mapping and number of shards.
func OpenShardedIndex ¶
func OpenShardedIndex(path string) (ShardedIndex, error)
OpenShardedIndex opens a sharded index at the specified path.
