More efficient unique indexes for monotonically increasing keys and constraints
Currently an index on a SERIAL and other monotonically increasing keys only add to the last node in the index causing the node to split into two half filled nodes. Eventually a sufficient number of nodes have so split that the index's search effic...
Some customers are constrained and need to continue to use Informix 32-bit CSDK drivers. Their applications currently use the Informix 32-bit libraries & there are often build constraints to moving to a 64-bit CSDK.
Consolidate free space across entire chunk or dbspace
I suggest a repack-like tool which consolidates free space in an entire chunk or dbspace in order to get few, big enough, free spaces to use efficiently. Being able to do so online and with little blocking is desirable
External tables are a great asset for ETL, and extending a bit the concept, they could be the base for a great ETL client.Often, one external table is the source of several ETL tasks, therefore it must be read sequentially several times, even if t...
To speedup backup time, it would be nice if Informix can read with more than 64k from disk. Example 12G SAS SSD - read 100 GByte with dd iflag=direct:Blocksize Throughput Time64k 197 MB/Sec 519 Sec (8:39)256k 438 MB/Sec 233 Sec (3:53)2048k 1186 MB...
Archecker table level restore utility does not compatible of handling Informix engine complex table schema clauses
Individual Table restoration 'archecker' utility only support simple schema definition contents as the schema file. However, Informix engine support complex clauses when setting up a table. E.g. When fragmenting a table based on interval based fra...
