Riak Search uses a custom backend called Merge Index. The Riak Search
backend is configurable in app.config, however, Merge Index is the only
backend that works for search:
{riak_search, [
{search_backend, merge_index_backend},
{java_home, "/usr"}
]},
Merge index is configurable in app.config as well:
%% Merge Index Config
{merge_index, [
{data_root, "data/merge_index"},
{buffer_rollover_size, 10485760},
{buffer_delayed_write_size, 524288},
{buffer_delayed_write_ms, 2000},
{max_compact_segments, 20},
{segment_query_read_ahead_size, 65536},
{segment_compaction_read_ahead_size, 5242880},
{segment_file_buffer_size, 20971520},
{segment_delayed_write_size, 20971520},
{segment_delayed_write_ms, 10000},
{segment_full_read_size, 20971520},
{segment_block_size, 32767},
{segment_values_staging_size, 1000},
{segment_values_compression_threshold, 0},
{segment_values_compression_level, 1}
]},
The data_root parameter will tell Merge Index where to store it's data
files.
Does this answer your question?
