Indexing in Big Data I have my data in gridb Database. To make the execution of my search query faster, I would like to do indexing on big data. Can we do indexing in GridDB? If yes, how?
It looks like you can index your data according to thier SQL documentation for CREATE INDEX. Sample code from their docs:
CREATE INDEX [IF NOT EXISTS] index_name ON table_name ( column_name_to_be_indexed );
GridDB's specifications and rules on index creation:

For a table, an index with the same name as an existing index in the table cannot be created.


If a transaction under execution exists in a table subject to processing, the system will wait for these to be completed before creating the data.


An index cannot be created on a column of BLOB type and ARRAY type.


Up to 16 columns can be indexed.


Time series table does not allow a primary key in a composite index.

My recommendation would be to index on the fields you plan to most commonly use in predicates (JOIN, WHERE, and HAVING clauses) in your queries, as a starting point.
